Abstract
In a nonvolatile memory system, data received from a host by a memory controller is transferred to an on-chip cache, and new data from the host displaces the previous data before it is written to the nonvolatile memory array. A safe copy is maintained in on-chip cache so that if a program failure occurs, the data can be recovered and written to an alternative location in the nonvolatile memory array.
