SYSTEMS AND METHODS OF STORING DATA

摘要

A method of writing data includes receiving a data page to be stored in a data storage device and initiating an encode operation to encode the data page. The encode operation generates first encoded data and a first portion of the first encoded data is stored to the first physical page of the data storage device. The method includes initiating storage of a second portion of the first encoded data to a second physical page of the data storage device. The method also includes initiating a decode operation to recover the data page. The decode operation uses a representation of the first portion of the first encoded data that is read from the first physical page without using any data from the second physical page.

1. A method of writing data, the method comprising:
in a data storage device with a controller and a memory die, wherein the controller includes an error correction coding (ECC) engine and wherein the memory die includes multiple physical pages including a first physical page and a second physical page, performing:
receiving a data page to be stored in the data storage device, wherein the data page is received from a host device;initiating an encode operation at the ECC engine to encode the data page, wherein the encode operation generates first encoded data;storing at least a portion of the first encoded data to the first physical page at the memory die;generating, at the memory die, second encoded data by:
reading a representation of the portion of the first encoded data from the first physical page; andgenerating redundant data at the memory die based on the representation of the portion of the first encoded data; andstoring the second encoded data to the second physical page.
