Patent ID: 8892842

Claim:
A memory system, comprising: a nonvolatile memory device; and a memory controller coupled to the nonvolatile memory device and configured to manage patterned data that is received by the memory system for storage in the nonvolatile memory device, the patterned data comprising repeated occurrences of a data pattern, wherein the memory controller is configured to comprise a random access memory and a nonvolatile memory, and wherein the memory controller is further configured to store the data pattern in the random access memory of the memory controller, and then transfer the data pattern of the random access memory into the nonvolatile memory of the controller at regular intervals and/or during an idle time, and wherein the memory controller is further configured to generate the patterned data responsive to the data pattern stored in the random access memory of the memory controller outside of the nonvolatile memory device in response to a read request for the pattern data which is issued before the data pattern is stored in the nonvolatile memory.
