摘要： Methods and apparatuses for a system error-correction code function are presented. The apparatus includes a memory configured to communicate with a host via at least one data connection and at least one non-data connection. The memory includes a memory array. The memory array includes a first portion and a second portion. The memory is further configured to, in a first mode, store and output data in the first portion and the second portion of the memory array. The first portion is addressable by a first address, and the second portion is addressable by a second address. The memory is further configured to, in a second mode, receive ECC of the data from the host via the at least one non-data connection, store the data in the first portion of the memory array, and store the ECC of the data in the second portion of the memory array based on the first address.

摘要： Aspects include systems and methods for increasing performance of a flash translation layer (FTL) of a flash memory device. A copy of FTL tables stored on a flash memory device may be copied to a memory of a host device. The copy of the FTL tables may be directly accessed by the flash memory device to translate between logical addresses provided by the host device for read/write operations from/to a flash memory of the flash memory device, and the respective physical addresses of the flash memory. The flash memory device is granted direct memory access to a portion of the memory of the host device where the copy of the FTL tables is stored. The flash memory device bus masters communication busses connecting the flash memory device to the memory of the host device.
