US 12,230,347 B2 · System and memory with configurable metadata portion

Abstract

Methods and apparatuses for a system error-correction code function are presented. The apparatus includes a memory configured to communicate with a host via at least one data connection and at least one non-data connection. The memory includes a memory array. The memory array includes a first portion and a second portion. The memory is further configured to, in a first mode, store and output data in the first portion and the second portion of the memory array. The first portion is addressable by a first address, and the second portion is addressable by a second address. The memory is further configured to, in a second mode, receive ECC of the data from the host via the at least one non-data connection, store the data in the first portion of the memory array, and store the ECC of the data in the second portion of the memory array based on the first address.

Dependent claims

An apparatus, comprising:

a memory configured to communicate with a host,
the memory comprising a memory array, the memory array comprising a first portion, a second portion, and a third portion;
the memory further configured to:
receive data from the host;
and
output the data to the host;
the memory further configured to, in a first mode:
store and output the data in the first portion and the second portion of the memory array, the first portion being addressable by a first address, the second portion being addressable by a second address;
generate first array error-correction code (ECC) based on the data in the first portion;
and
store the first array ECC in the third portion;
and
the memory further configured to, in a second mode:
store and output the data in the first portion, based on the first address;
receive metadata of the data from the host;
and
store and output the metadata in the second portion, based on the first address.
