Memory device and method with pre-read acceleration techniques

A method of operating a memory device, the method comprising:

• making a cache-hit determination for a read request received from a host in response to the read request;
• providing a memory processing unit with a pre-request for performing at least one operation of operations for determining data corresponding to the read request before completion of the cache-hit determination of the read request, wherein the pre-request corresponds to the read request or is a copy of the read request;
• performing the at least one operation in response to the reception of the pre-request;
• and
• returning data obtained from a memory module through the memory processing unit to the host in a case of the cache-hit determination determining a cache miss, and returning data hit in the cache to the host in a case of the cache-hit determination determining a cache hit.

A method performed by a compressed memory device comprising a cache and a memory module storing compressed data, the method comprising:

• receiving, from a host, a read request for data, the read request comprising a host address;
• based on the read request, making a determination that a cache-hit occurs for the host address in the cache;
• based on receiving the read request, and before the determining of the cache-hit is completed, initiating operations to retrieve the data from memory module;
• and
• based on the determining that the cache-hit occurred, aborting or not completing the operations to retrieve the data from the memory module.
