US 12,118,222 B2 · Controlling memory overhead for storing integrity data in solid state drives

Abstract

This application is directed to data protection in a memory system of an electronic device. The memory system has a first memory block and a second memory block, and each memory block includes one or more respective memory dies. Each memory die of the second memory block is distinct from the one or more respective memory dies of the first memory block. The electronic device stores user data including a plurality of user data items in the first memory block and integrity data including a plurality of integrity data items in the second memory block. Each of the plurality of user data items is configured to be validated based on a respective one of the plurality of integrity data items. The electronic device invalidates the integrity data in the second memory block, and reads the user data from the first memory block independently of the integrity data.

Dependent claims

A data storage method, comprising:

at an electronic device having a memory system, the memory system having a first memory block and a second memory block, each memory block including one or more respective memory dies:
storing user data including a plurality of user data items in the first memory block, each of the plurality of user data items configured to be validated based on a respective one of a plurality of integrity data items;
storing integrity data including the plurality of integrity data items in the second memory block, each memory die of the second memory block being distinct from the one or more respective memory dies of the first memory block;
invalidating the integrity data in the second memory block;
and
reading the user data from the first memory block independently of the integrity data.

3 more elements

An electronic device, comprising:

one or more processors;
a memory system having a first memory block and a second memory block, each memory block including one or more respective memory dies;
and
memory storing one or more programs for execution by the one or more processors, the one or more programs including instructions for:
storing user data including a plurality of user data items in the first memory block, each of the plurality of user data items configured to be validated based on a respective one of a plurality of integrity data items;
storing integrity data including the plurality of integrity data items in the second memory block, each memory die of the second memory block being distinct from the one or more respective memory dies of the first memory block;
invalidating the integrity data in the second memory block;
and
reading the user data from the first memory block independently of the integrity data.

6 more elements

A non-transitory computer-readable storage medium storing one or more programs for execution by one or more processors, the one or more programs comprising instructions for:

at an electronic device having a memory system, the memory system having a first memory block and a second memory block, each memory block including one or more respective memory dies;
storing user data including a plurality of user data items in the first memory block, each of the plurality of user data items configured to be validated based on a respective one of a plurality of integrity data items;
storing integrity data including the plurality of integrity data items in the second memory block, each memory die of the second memory block being distinct from the one or more respective memory dies of the first memory block;
invalidating the integrity data in the second memory block;
and
reading the user data from the first memory block independently of the integrity data.
