    Abstract: A nested wrap-around technology includes an address counter and associated logic for generating addresses to perform a nested wrap-around access operation. The nested wrap-around access operation may be a read or a write operation. A wrap-around section length and a wrap-around count define a wrap-around block. A wrap starting address, initially set to a supplied start address, is offset from a lower boundary of a wrap-around section. Access starts at a wrap starting address and proceeds in a wrap-around manner within a wrap-around section. After access of the address immediately preceding the wrap starting address, the wrap starting address is incremented by the wrap-around section length, or, if the wrap-around section is the last one in the wrap-around block, the wrap starting address is set to the lower boundary of the wrap-around block plus the offset. Access continues until a termination event.

    Abstract: A method of operating a memory storing data sets, and ECCs for the data sets is provided. The method includes when writing new data in a data set, computing and storing an ECC, if a number of addressable segments storing the new data and data previously programmed in the data set includes at least a predetermined number of addressable segments. The method includes storing indications for whether to enable or disable use of the ECCs, using the ECC and a first additional ECC bit derived from the ECC. The method includes reading from a data set an extended ECC including an ECC and a first additional ECC bit derived from the ECC, and enabling or disabling use of the ECC according to the indications stored for the data set. The method includes enabling use of ECCs for blank data sets, using the indications and a second additional ECC bit.

    Abstract: An integrated circuit device includes a pad adapted to receive a signal from an external driver. A state register is programmed with a state that indicates a voltage level to set for the pad during initialization of circuitry on the integrated circuit device responsive to the state for the pad. The voltage level may correspond to a logic low level or a logic high level. A voltage holding circuit is coupled to the pad and the state register, and is configured to force the pad to the voltage level in response to an event that causes the initialization.

    Abstract: A memory device and an associated control method are provided. The memory device includes a non-volatile memory array and a memory control circuit. The non-volatile memory array includes M secured memory zones. The memory control circuit is electrically connected to the non-volatile memory array. The memory control circuit provides a set of mapping information and searches a request key in the set of mapping information. The set of mapping information represents correspondences between N access keys and the M secured memory zones. The memory control circuit acquires at least one of the M secured memory zones if the request key is one of the N access keys, and performs an access command to the at least one of the M secured memory zones. M and N are positive integers.

    Abstract: A memory device comprises a memory array with I/O path and security circuitry coupled to the I/O path of the memory array. The memory device comprises control circuitry, responsive to configuration data, to invoke the security circuitry. The memory device comprises a configuration store, storing the configuration data accessible by the control circuitry to specify location and size of a security memory region in the memory array. Responsive to an external command and the configuration data, the control circuitry can be configured to invoke the security circuitry on an operation specified in the external command in response to accesses into the security memory region, or to not invoke the security circuitry in response to accesses to outside the security memory region.
