Method and apparatus to perform concurrent read and write memory operations

A memory microcontroller comprising:

• an interface to connect to a memory array;
• and
• electronic circuitry configured to:
• suspend calculation of an error correction code (ECC) in response to receiving a read request to read contents of the memory array;
• while writing to the memory array, determine one or more of the contents of the memory array based on stored ECC;
• and
• subsequently resume calculating the ECC.

A system comprising:

• a memory device comprising a memory, the memory device further comprising a memory microcontroller configured to:
• suspend calculation of an error correction code (ECC) in response to receiving a read request to read contents of the memory;
• while writing to the memory, determine at least one content of the memory based on stored ECC;
• and
• subsequently resume calculating the ECC;
• and
• a processor to host one or more applications and to initiate the read request to the memory microcontroller to provide access to the memory.
