METHODS, SYSTEMS, AND COMPUTER READABLE MEDIA FOR ADDRESS AND DATA INTEGRITY CHECKING IN FLASH MEMORY OPERATIONS

摘要

Methods, systems, and computer readable media for address and data integrity checking in flash memory operations are disclosed. One method includes, at a storage controller, generating, for an address unit, an address parity unit. The method further includes generating a command sequence including the address unit, the address parity unit, and an operation command specifying an operation to be performed on a flash memory array. The method further includes providing the command sequence to a flash memory device that includes the non-volatile memory array. The method further includes performing, by the flash memory device, an address integrity check on the address unit using the address parity unit. The method further includes determining whether or not to perform an operation specified by the command sequence based at least in part on a result of the address integrity check.

1. A method for integrity checking in flash memory operations, the method comprising:
at a controller, generating an address parity unit for an address unit and generating a command sequence including the address unit, the address parity unit, and an operation command specifying an operation to be performed on a flash memory array; communicating the command sequence to a flash memory device that includes the flash memory array; performing, by the flash memory device, an address unit integrity check using the address unit address parity unit; and determining whether or not to perform the operation specified by the operation command based at least in part on a result from the address integrity check.
