Locked raid with compression for memory interconnect applications

A device comprising:

• an interface configured to operatively couple to a plurality of memory devices arranged in a locked redundant array of independent disks (LRAID), the memory devices of arranged in the LRAID being configured to store a plurality of stripes of data, and each of the stripes spanning over the memory devices;
• and
• control circuitry operatively coupled to the interface and at least configured to:
• obtain data;
• generate parity data based on the obtained data;
• perform data compression on the obtained data to generate compressed data;
• store the compressed data in at least a first stripe of the plurality of stripes of data;
• determine an amount of storage space of the memory devices needed to store the compressed data in the first stripe;
• and
• determine which one of the plurality of stripes will store the parity data of the first stripe based at least on the amount of storage space of the memory devices required to store the compressed data in the first stripe.

A method comprising:

• operatively coupling an interface to a locked redundant array of independent disks (LRAID) including M memory dice, the M memory dice of the LRAID being configured to store a plurality of stripes of data, and each of the stripes spanning over the M memory dice and wherein M is an integer greater than 1;
• obtaining data;
• performing data compression on the obtained data to generate compressed data;
• storing the compressed data in the plurality stripes of data;
• generating parity data of each of the stripes;
• determining, for each of the stripes, a number of memory dice required to store the compressed data;
• determining, for each of the stripes whether the number of memory dice that is required to store the compressed data in each of the stripes is N memory dice or less;
• wherein N is an integer less than M;
• and
• determining, for each of the stripes, which of the plurality of stripes will store the parity data of that one of the stripes based at least on the determination of whether the number of memory dice required to store the compressed data in the one of the stripes is N memory dice or less.
