Apparatus and methods for providing data integrity

摘要

The present disclosure includes apparatus (e.g., computing systems, memory systems, controllers, etc.) and methods for providing data integrity. One or more methods can include, for example: receiving a number of sectors of data to be written to a number of memory devices; appending first metadata corresponding to the number of sectors and including first integrity data to the number of sectors, the first metadata has a particular format; generating second integrity data to be provided in second metadata, the second integrity data corresponding to at least one of the number of sectors (wherein the second metadata has a second format); and generating third integrity data to be provided in the second metadata, the third integrity data including error data corresponding to the second integrity data and the at least one of the number of sectors.

主权项

1. An apparatus, comprising:
a first controller component configured to append first metadata to one or more sectors of data to be written to one or more memory devices, the first metadata having a first format and including first integrity data; a second controller component configured to generate second integrity data to be provided in second metadata having a second format and including at least a portion of the first metadata, wherein the second integrity data covers at least one of the one or more sectors and the at least a portion of the first metadata; and a third controller component configured to generate third integrity data to be provided in the second metadata, wherein the third integrity data includes error data covering the second integrity data and the at least one of the one or more sectors.
