Memory subsystem with wrapped-to-continuous read

A system comprising:

• a plurality of memory devices;
• a memory controller comprising
• a decoder configured to receive two or more requests for data stored across at least a first memory area and a second memory area of the plurality of memory devices, wherein the two or more requests for data are received from a CPU of a host;
• a merge detect module configured to determine that the first memory area is adjacent to the second memory area and responsively merge the received two or more requests for data into a single request for data across at least the first memory area and the second memory area, and update a read length associated with the single request such that the updated read length encompasses at least the first memory area and the second memory area;
• a processor configured to:
• perform a wrapped read of data within the first memory area, and
• responsive to the single request and using the updated read length, perform a continuous read of data within the second memory area, wherein the continuous read starts at a first boundary of the second memory area;
• wherein after reading a final address of the wrapped read of data within the first memory area, the processor automatically starts the continuous read of data at a first boundary of the second memory area.

A tangible computer-readable device having instructions stored upon that, when executed by at least one computing device, causes the at least one computing device to perform operations comprising:

• receiving two or more requests for data stored across at least a first memory area and a second memory area of a memory, wherein the two or more requests for data are received from a CPU of a host;
• merging the received two or more requests for data into a single request for data across at least the first memory area and the second memory area, and updating a read length such that the updated read length encompasses at least the first memory area and the second memory area;
• based on the single request,
• performing a wrapped read of data within the first memory area of the memory;
• and
• performing a continuous read of data within the second memory area of the memory using the updated read length, the second memory area being adjacent to the first memory area, wherein the continuous read starts at a first boundary of the second memory area, and is performed automatically after reading a final address of the wrapped read of data within the first memory area;
• and
• controlling a timing of the performing of the wrapped read and a timing of the performing of the continuous read using a state machine.
