Abstract: A removable electronic circuit card (33) having multiple modules, such a memory module with a non-volatile mass storage memory and a separate input-output (37a) module, where data transfers may be made through the a first module directly to and from the another in a direct memory access (DMA) type transfer when the card is inserted into the host system (31) but without having to pass the data through the host system. Once the host gives a DMA command, the data transfer is accomplished independently of the host system, except for the host supplying power and possibly a clock signal and other like support, during such a data transfer directly with card. The data for the transfer can be communicated between the input-output module and the exterior device through either wireless or an electrical connection means.

Abstract: In order to maintain the integrity of data stored in a flash memory that are susceptible to being disturbed by operations in adjacent regions of the memory, disturb events cause the data to be read, corrected and re-written before becoming so corrupted that valid data cannot be recovered. The sometimes conflicting needs to maintain data integrity and system performance are balanced by deferring execution of some of the corrective action when the memory system has other high priority operations to perform. In a memory system utilizing very large units of erase, the corrective process is executed in a manner that is consistent with efficiently rewriting an amount of data much less than the capacity of a unit of erase. Data is rewritten when severe errors are found during read operations. Portions of data are corrected and copied within the time limit for read operation. Corrected portions are written to dedicated blocks.

Abstract: A memory system comprises an encryption engine implemented in the hardware of a controller. In starting up the memory system, a boot strapping mechanism is implemented wherein a first portion of firmware when executed pulls in another portion of firmware to be executed. The hardware of the encryption engine is used to verify the integrity of at least the first portion of the firmware. Therefore, only the firmware that is intended to run the system will be executed.

Abstract: In a non-volatile memory system, test data may be retrieved by means of a circuit without the help of firmware. The circuit is triggered into action when it detects an abnormality in the processor or host interface. In such event, it formats the self test or status signals from the various blocks in the non-volatile memory system controller and sends a test message to the outside world without the assistance of the system processor or interface controller. When implemented in memory systems with multiple data lines, only one of the data lines may be utilized for such purpose, thereby allowing the testing to be performed while the system is still performing data transfer. Preferably, the system includes the test mode communication controller, which can select between a test channel and a host interface channel for the test message transfer so that the same testing may be performed when the memory system is in the test package as well as in an encapsulated package. The test message is transmitted repeatedly and the test message is structured so that it is easier for the receiver host to decipher the message without a handshake with the memory system. A communication controller preferably detects whether any of the communication channels is not used by the controller of a non-volatile memory system for sending signals and sends diagnostic signals through such channel.

Abstract translation: 在非易失性存储器系统中，测试数据可以通过电路在没有固件的帮助下检索。 当检测到处理器或主机接口中的异常时，电路被触发成动作。 在这种情况下，它会从非易失性存储器系统控制器中的各个块格式化自检或状态信号，并在没有系统处理器或接口控制器的帮助的情况下向外界发送测试消息。 当在具有多个数据线的存储器系统中实现时，只有一个数据线可以用于此目的，从而允许在系统仍然执行数据传输时执行测试。 优选地，该系统包括测试模式通信控制器，其可以在测试信道和用于测试消息传送的主机接口信道之间进行选择，使得当存储器系统处于测试包中时也可以执行相同的测试 封装包装。 测试消息被重复发送，并且测试消息被构造成使得接收者主机更容易解密消息而不与存储器系统进行握手。 通信控制器优选地检测用于发送信号的非易失性存储器系统的控制器是否没有使用任何通信信道，并且通过这样的信道发送诊断信号。

Abstract: A memory card that adapts its operation according to the application to which it applied or the conditions under which it is operated. This allows the card to dynamical self optimize. In a first set of embodiments, the card uses host profiling where it will learn about the host during host-card interactions and the card's controller will optimize its algorithms accordingly. In another set of embodiments, the host and card will report to one another their capabilities for a quality of service negotiation. A further set of embodiments allows the storage device to memorize access sequences issued by the host under various predefined conditions, such as host reset or a power on boot sequence. The storage device can use this information to optimize operation for the expected commands. On deviation from an expected sequence, the device would memorize the new command sequence and save it, thus operating in a self-adaptive manner.

Abstract: Methods and systems for working around the timeout limitations of physical interface standards for detachable modules. By use of dummy data blocks to keep the bus active, the bus timeout requirements (in either direction) can be spoofed, to thereby permit more complex processing operations to be performed, which otherwise might not fit reliably within the timeout period. This permits a memory system to execute applications or process data for a time period that may exceed the bus timeout of a particular specification. A controller in the memory system deasserts the ready signal and holds the bus connecting the computer system in a "busy" state until the memory system is about to timeout. During a write operation, the controller receives dummy data blocks from the computer system before the write bus timeout period expires, causing the bus timeout period to be reset. During a read operation, the controller sends dummy data blocks to the computer system before the read bus timeout period expires, causing the bus timeout period to be reset.

Abstract translation: 用于解决可拆卸模块的物理接口标准的超时限制的方法和系统。 通过使用伪数据块来保持总线活动，可以欺骗总线超时要求（在任一方向），从而允许执行更复杂的处理操作，否则可能在超时时间段内不可靠地适应。 这允许存储器系统在可能超过特定规范的总线超时的时间段内执行应用程序或处理数据。 存储器系统中的控制器取消准备就绪信号并将连接计算机系统的总线保持在“忙碌” 直到内存系统即将超时。 在写入操作期间，控制器在写入总线超时周期到期之前从计算机系统接收虚拟数据块，导致总线超时周期被重置。 在读操作期间，控制器在读总线超时周期到期之前向计算机系统发送伪数据块，导致总线超时周期被重置。

Abstract: When cipher block chaining encryption/decryption is employed, write fault recovery is accomplished by storing information useful for the writing of cipher block chaining processed data before it is written to storage cells. Hence when write failure is discovered, this information stored can be retrieved for rewriting the data to the cells. Preferably, the information stored includes security configuration information for cipher block chaining processing a unit of data.

Abstract: A flash non-volatile memory system that normally operates its memory cells in multiple storage states is provided with the ability to operate some selected or all of its memory cell blocks in two states instead. The two states are selected to be the furthest separated of the multiple states, thereby providing an increased margin during two state operation. This allows faster programming and a longer operational life of the memory cells being operated in two states when it is more desirable to have these advantages than the increased density of data storage that multi-state operation provides. An exemplary embodiment is as a memory card where the user can choice between two state and multi-state operation.
