Abstract
Apparatuses, systems, and methods for alternate memory die metadata storage. A memory module includes a number of memory devices. A controller writes data and metadata to the module. The data is stored in the memory devices, while the metadata is stored in a selected portion of the memory devices. The selected portion of the memory devices may use separate write enable signals to protect bit lines which the metadata is not being written to.
Claims22
An apparatus comprising:
- a plurality of memory devices;
- and
- a controller, wherein the controller is configured to provide a plurality of data bits and a plurality of metadata bits as part of a write operation, wherein each of the plurality of memory devices receives a respective portion of the plurality of data bits and a selected portion of the plurality of memory devices receives a respective portion of the plurality of metadata bits, wherein the selected portion comprises less than all of the plurality of memory devices.
A method comprising:
- receiving a plurality of data bits and an associated plurality of metadata bits with a memory module comprising a plurality of memory devices;
- writing a respective portion of the plurality of data bits to each of the plurality of memory devices;
- and
- writing a respective portion of the plurality of metadata bits to selected ones of the plurality of memory devices,
- wherein the selected ones comprises less than all of the plurality of memory devices.
2 more elements
An apparatus comprising:
- a first memory device;
- a second memory device;
- and
- a module logic circuit configured to provide a read command to the first memory device and the second memory device,
- wherein responsive to the read command the first memory device is configured to provide a first portion of a plurality of data bits and the second memory device is configured to provide a second portion of a plurality of data bits and a selected one of the first memory device or the second memory device is configured to provide a plurality of metadata bits associated with the plurality of data bits.
2 more elements
An apparatus comprising:
- a memory module comprising a plurality of memory devices, wherein the memory module is a 10×2p2 memory module;
- and
- a controller, wherein the controller is configured to provide a plurality of data bits and a plurality of metadata bits as part of a write operation, wherein each of the plurality of memory devices receives a respective portion of the plurality of data bits and a selected portion of the plurality of memory devices receives a respective portion of the plurality of metadata bits.
A method comprising:
- receiving a plurality of data bits and an associated plurality of metadata bits with a memory module comprising a plurality of memory devices, wherein the memory module is a 10×2p2 memory module;
- writing a respective portion of the plurality of data bits to each of the plurality of memory devices;
- and
- writing a respective portion of the plurality of metadata bits to selected ones of the plurality of memory devices.
