Abstract:
A nonvolatile memory controller performs a data stripe operation on data blocks by processing a collection of commands. The nonvolatile memory controller includes command processing units, each of which processes a command of the data stripe operation to store a data block into a nonvolatile memory device. A parity calculator in the nonvolatile memory controller receives the data blocks of the data stripe operation by receiving a sequence of data blocks. The parity calculator generates a parity block in a page frame as the parity calculator receives the sequence of the data blocks. A command processing unit in the nonvolatile memory controller determines when the parity calculator has completed generating the parity block and writes the parity block to a nonvolatile memory device.
