Memory system for secure read and write operations based on predefined data patterns

Abstract

A memory buffer device facilitates secure read and write operations associated with data that includes a predefined data pattern. For read operations, the memory buffer device detects a read data pattern in the read data that matches a predefined data pattern. The memory buffer device may then generate a read response that includes metadata identifying the read data pattern without sending the read data itself. The memory buffer device may also receive Write Request without Data (RwoD) commands from the host that include metadata identifying a write data pattern. The memory buffer device identifies the associated data pattern and writes the data pattern or the metadata to the memory array. The memory buffer device may include encryption and decryption logic for communicating the metadata in encrypted form.
