Abstract: In a nonvolatile memory system a Soft-Input Soft-Output (SISO) decoder corrects errors in data that is read from a memory and a statistical unit connected to the SISO decoder collects data regarding corrections. The statistical unit generates at least one output based on the collected data and at least one operating parameter of the memory is modified in response to the output.

Abstract: Data is read from a nonvolatile memory array using one or more read voltages that are adjusted during memory life. Programming target voltages and read voltages may be adjusted together over memory life to map memory states to an increasingly wide threshold window. Individual memory states are mapped to sub-ranges that are made wider, reducing errors.

Abstract: A buffer cache interposed between a non-volatile memory and a host may be partitioned into segments that may operate with different policies. Cache policies include write-through, write and read-look-ahead. Write-through and write back policies may improve speed. Read-look-ahead cache allows more efficient use of the bus between the buffer cache and non-volatile memory. A session command allows data to be maintained in volatile memory by guaranteeing against power loss.

Abstract: An improved flash EEPROM memory-based storage subsystem includes one or more flash memory arrays, each with a duplicity of data registers and a controller circuit. When data are read from a flash array into a data register, the data is copied to a second register so that, during the ensuing program operation into the same array, the data may be transferred to the controller for the purpose of checking the data validity. This creates an improved performance system that doesn't suffer data transfer latency during copy operations but that is able to guarantee the validity of the data involved in such operations.

Abstract translation: 改进的基于闪存的EEPROM存储子系统包括一个或多个闪存阵列，每个闪存阵列都有一个数据寄存器和一个控制器电路。 当数据从闪存阵列读入数据寄存器时，数据被复制到第二个寄存器，以便在随后的程序操作进入同一个阵列的过程中，可以将数据传送到控制器以检查数据有效性 。 这创建了一个改进的性能系统，它在复制操作期间不会遭受数据传输延迟，但能够保证涉及这些操作的数据的有效性。

Abstract: Data are encoded using convolutional coding prior to storage in a nonvolatile memory array, so that errors that occur when the data are read may be corrected even where there is a large number of such errors. Coding rates of less than one increase the amount of data to be stored but allow correction of large numbers of errors.

Abstract: A non-volatile memory device is provided with a controller and includes method that controls memory operations and to emulate the memory and communication characteristics of a legacy memory device. In this way, the memory device is compatible with a host that was originally designed to operate the legacy memory device. In particular, the controller performs the emulation to the host taking into account differences such as multibit memory, error correction requirement, memory support of overwrites, and erasable block sizes.

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.

Abstract: A detachable memory module is interposed between a host and a disk drive. The memory module includes a solid-state nonvolatile memory used for caching data sent by the host for storage in the disk drive. Caching takes place under the control of a memory controller in the memory module and may be transparent to the host. The disk drive may remain spun-down when data is cached, saving power. The destination for host data may be determined based on desired speed, power consumption and expected need for that data. A host may send specific commands to the memory module to enable additional functions.

Abstract: The present invention present methods and architectures for the pipelining of read operation with write operations. In particular, methods are presented for pipelining data relocation operations that allow for the checking and correction of data in the controller prior to its being re-written, but diminish or eliminate the additional time penalty this would normally incur. A number of architectural improve are described to facilitate these methods, including: introducing two registers on the memory where each is independently accessible by the controller; allowing a first memory register to be written from while a second register is written to; introducing two registers on the memory where the contents of the registers can be swapped.
