US 2026/0029936 A1 · READ BOOSTER FOR OPERATIONAL DATA OF A MEMORY SYSTEM

Abstract

Methods, systems, and devices for read booster for operational data of a memory system are described. A memory system may access system-related data in a partition via a mapping table stored in volatile memory as opposed to loading multi-level logical-to-physical tables from non-volatile memory. For example, a host system may provide a logical block address (LBA) range of system-related data to be written to the partition using a first command. The memory system may contiguously store physical block addresses (PBAs) corresponding to the LBA range into one or more segments of the partition. To access a given PBA in a segment, the memory system may access one or more parameters stored in the mapping table, such as a starting PBA and size (e.g., in PBAs) for each respective segment.

Claims25

Dependent claims

A memory system, comprising:

one or more memory devices;
and
processing circuitry coupled with the one or more memory devices and configured to cause the memory system to:
receive a first command that indicates a range of logical block addresses associated with storing information for an operating system, the range of logical block addresses having a starting logical block address and a quantity of logical block addresses in the range of logical block addresses;
store data to contiguous physical block addresses in the memory system in accordance with receiving the first command, wherein the contiguous physical block addresses are associated with the range of logical block addresses;
and
read the data from the contiguous physical block addresses in accordance with storing the data and with a starting physical block address, a first quantity of addresses of the contiguous physical block addresses, and a logical block address of the range of logical block addresses.

4 more elements

A non-transitory computer-readable medium storing code comprising instructions which, when executed by one or more processors of a memory system, cause the memory system to:

receive a first command that indicates a range of logical block addresses associated with storing information for an operating system, the range of logical block addresses having a starting logical block address and a quantity of logical block addresses in the range of logical block addresses;
store data to contiguous physical block addresses in the memory system in accordance with receiving the first command, wherein the contiguous physical block addresses are associated with the range of logical block addresses;
and
read the data from the contiguous physical block addresses in accordance with storing the data and with a starting physical block address, a first quantity of addresses of the contiguous physical block addresses, and a logical block address of the range of logical block addresses.
