US 10,949,291 B2 · Partially written superblock treatment

Abstract

The present disclosure relates to partially written superblock treatment. An example apparatus includes a memory device operable as a multiplane memory resource including blocks organized as superblocks. The memory device is configured to maintain, internal to the memory device, included in a status of an open superblock, a page indicator corresponding to a last written page of the open superblock. The memory device is further configured, responsive to receipt, from a controller, of a read request to a page of the open superblock, determine from page map information maintained internal to the memory device and from the indicator of the last written page, which of a number of different read trim sets to use to read the page of the open superblock corresponding to the read request.

Dependent claims

An apparatus, comprising:

a memory device operable as a multiplane memory resource comprising blocks organized as superblocks;
wherein the memory device includes instructions stored thereon that when executed by a controller, internal to the memory device, cause the controller to direct the memory device to:
maintain, internal to the memory device, a status of a number of open superblocks in the memory device, the status comprising an indicator of a write operation initiated in the number of the open superblocks;
and
responsive to receipt, by the controller, of a read request to a page of an open superblock, determine from page map information maintained internal to the memory device and from an indicator of a last written page of the open superblock, which of a number of different read trim sets to use to read the page of the open superblock corresponding to the read request.

A method comprising:

receiving, by a memory device comprising a plurality of blocks, a read request including an identifier of each block of an open superblock and a page identifier;
comparing the identifier of each block to a maintained status of the open superblock;
and
responsive to determining that the identifier of each block matches the maintained status determining, from page map information comprising a page programming order and an indicator of a last written page of the open superblock maintained internal to the memory device, which of a number of different read trim sets to use to read a page corresponding to the read request.
