    Abstract: A synchronous flash memory includes an array of non-volatile memory cells. The memory array is arranged in rows and columns, and can be further arranged in addressable blocks. Data communication connections are used for bi-directional data communication with an external device(s), such as a processor or other memory controller. The memory can output data from storage registers on the data communication connections during a series of clock cycles to provide a burst of register data. The memory can also provide the register data in accordance to a defined clock latency value. The register data can include status data, operating setting data, manufacture identification, and memory device identification.

    Abstract: A secure microprocessor is designed using quad-coded logic which is similar to dual-rail encoded asynchronous logic except that the '11' state propagates an alarm. The alarm signal obliterates secure data in its path. Quad-coded logic provides resilience to power glitches and single-transistor or single-wire failures. The already low data dependency of the power consumption makes power analysis attacks difficult, and they are made even more difficult by inserting random delays in data and control paths, and by a set-random-carry instruction which enables software to make a non-deterministic choice between equivalent instruction sequences. These features are particularly easy to implement well in quad-coded logic.

    Abstract translation: 使用四路编码逻辑设计安全微处理器,类似于双轨编码异步逻辑,除了“11”状态传播报警。 报警信号在其路径中消除了安全数据。 四通道逻辑为电源故障和单晶体管或单线故障提供了弹性。 功耗的已经很低的数据依赖性使得功率分析攻击变得困难,并且通过在数据和控制路径中插入随机延迟以及通过设置随机携带指令使得软件变得非确定性 等效指令序列之间的选择。 这些特性在四代码逻辑中特别容易实现。

    Abstract: A synchronous flash memory includes an array of non-volatile memory cells. The memory device has a package configuration that is compatible with an SDRAM. The memory device can comprise an array of memory cells having N addressable sectors, and control circuitry to control erase or write operations on the array of memory cells. Protection circuitry can be coupled to the control circuitry to selectively prevent erase or write operations from being performed on both first and last sectors of the N addressable sectors. The protection circuitry can comprise a multi-bit register having a first bit corresponding to the first sector and a second bit corresponding to the last sector.

    Abstract: A system is disclosed for isolating a bond pad (2) from the rest of the circuitry of a semiconductor chip (4) in a manner that protects the chip from applied signals that are outside the normal operating range and which tamper with the operation of the system. The system includes the use of a controllable switch (8) for routing the signal from the bond pad to the circuit and a detector for detecting a tamper condition on the bond pad. The detection of a tamper condition causes the detector to inform the microcontroller on the chip to, for example, terminate the operation in progress, perform a controlled system shutdown, disable pre-arranged functions, or record the fact that a tamper condition occurred.

    Abstract: The invention is a method and system in which an authentication chip having secret information stored within it, including secret data stored in multi-level flash memory, is protected from unauthorised modification of values stored in the flash memory. The secret information is stored using an internal command and can only be accessed by one or more further commands. Secret data in the information is stored in intermediate states of the multi-level flash memory between the minimum and maximum voltage level states. A validity check is performed on secret data items before allowing them to be read out by a command accessing them. The validity check involves calculation of a checksum and comparison of the result with a checksum stored using the internal command as part of the secret information.
