Self-managed dram modules with built-in adaptive data compression

A method of compressing data for a self-managed dynamic random-access memory (DRAM) module, comprising:

• compressing a data chunk to generate a plurality of compression results, wherein each compression result includes a different block size;
• identifying an optimal compression result, wherein the optimal compression result has a lowest block size among the plurality of compression results that achieves a threshold compression;
• and
• storing the optimal compression result in at least one of a plurality of DRAM chips of the self-managed DRAM module.

A self-managed dynamic random-access memory (DRAM) module, comprising:

• a plurality of DRAM chips;
• and
• a controller chip configured to compress a data chunk received from a host according to a process that includes:
• applying LZ compression on the data chunk to generate an LZ compressed block;
• applying entropy coding to the LZ compressed block to generate an LZ/entropy compressed block;
• and
• evaluating a read latency of the LZ compressed block and the LZ/entropy compressed block;
• and
• selecting one of the LZ compressed block or the LZ/entropy compressed block for storage in at least one of the DRAM chips based on the read latencies of the LZ compressed block and the LZ/entropy compressed block.
