Identification of non-volatile memory die for use in remedial action

摘要

Embodiments of apparatus, methods, storage drives, computer-readable media, systems and devices are described herein for identification of die of non-volatile memory for use in remedial action. In various embodiments, a first block may be configured to encode data to be stored in a non-volatile memory as a codeword. In various embodiments, the first block may be configured to store respective portions of the codeword in a distributed manner across a plurality of die of the non-volatile memory. In various embodiments, the first block may be configured to generate respective error detection codes for the plurality of die.

主权项

1. An apparatus comprising:
a first block configured to encode data to be stored in a non-volatile memory as a codeword, to store respective portions of the codeword in a distributed manner across a plurality of die of the non-volatile memory, and to generate respective error detection codes for the plurality of die; and a second block coupled to the first block and configured to identify a first die of the plurality of die for use in remedial action, based on a determination related to the error detection codes that more sub-portions of a first portion of the codeword stored on the first die include an error than sub-portions of a second portion of the codeword stored on a second die of the plurality of die.
