Integrated memory management and memory management method

A memory unit comprising;

• a plurality of non-volatile memory units formed on a substrate, wherein the non-volatile memory units are a main memory of the processor;
• and
• a memory management unit formed on the substrate and connected to the non-volatile memory units, and connectable to a processor, comprising,
• an acquiring unit acquiring logical addresses from the processor;
• an address conversion unit converting logical addresses acquired by the acquiring unit into physical addresses of the non-volatile memory units;
• and
• an access unit reading data from memory areas of the non-volatile memory units designated by physical addresses at reading, and writing data to memory areas of the non-volatile memory units designated by physical addresses at writing, wherein each non-volatile memory unit includes at least two regions and the access unit determines which region to write writing data based on access frequency information associated with the writing data and the memory management unit includes an RAID function for the non-volatile memory units, and a swap target non-volatile memory unit is able to swap when another non-volatile memory unit is operating.

A memory management method comprising:

• acquiring logical addresses from a processor;
• converting logical addresses into physical addresses of a non-volatile main memory;
• and
• reading data from memory areas of the non-volatile main memory designated by physical addresses, or writing data to memory areas of the non-volatile main memory designated by physical addresses,
• wherein when writing data, determine which regions of the non-volatile main memory to write writing data based on access frequency information associated with the writing data.
