Title:
CODE RATE SWITCHING MECHANISM FOR FLASH MEMORY
Document Type and Number:
WIPO Patent Application WO/2019/139836
Kind Code:
A1
Abstract:
A data storage system capable of switching a code rate based on a host command is disclosed. A controller of the data storage system may set a code rate in a data storage device to a first code rate for encoding data to be written to non-volatile memory of the data storage device. The controller may receive, at the data storage device, a host command indicating a switch point for switching the set code rate from the first code rate to a second code rate. The controller may switch the set code rate from the first code rate to the second code rate at the indicated switch point.
