Non-volatile write buffer data retention pending scheduled verification

摘要

Method and apparatus for managing data in a memory. In accordance with some embodiments, a non-volatile (NV) buffer is adapted to store input write data having a selected logical address. A write circuit is adapted to transfer a copy of the input write data to an NV main memory while retaining the stored input write data in the NV buffer. A verify circuit is adapted to perform a verify operation at the conclusion of a predetermined elapsed time interval to verify successful transfer of the copy of the input write data to the NV main memory. The input write data are retained in the NV buffer until successful transfer is verified.

1. A method comprising:
storing input write data in a non-volatile (NV) buffer, the input write data having an associated logical address; transferring a copy of the input write data to an NV main memory while retaining the stored input write data in the NV buffer; initiating a count to denote a predetermined elapsed time interval; and performing a verify operation at responsive to the conclusion of the predetermined elapsed time interval to verify successful transfer of the copy of the input write data to the NV main memory.
