Concurrent memory operations for read operation preemption

A method, comprising:

• performing by a memory transaction control logic, a write operation in a non-volatile memory in response to a write command received by the memory transaction control logic;
• receiving by the memory transaction control logic, a command while performing the write operation;
• in response to the received command, suspending by the memory transaction control logic, the performing of the write operation;
• performing by the memory transaction control logic, a read operation while the write operation is suspended;
• transferring by a controller, read data of the read operation from the memory;
• and
• concurrently with at least a portion of the read data transferring from the memory, resuming by the memory transaction control logic, the performing of the write operation.

A system, comprising:

• a central processing unit;
• a non-volatile memory including an array of bit cells;
• and
• a non-volatile memory interface for the central processing unit and the array of bit cells;
• wherein the central processing unit is configured to generate and transmit to the non-volatile memory interface, a memory transaction request and a system address at which the memory transaction is to take place;
• and wherein the non-volatile memory interface includes:
• write operation logic configured to receive a write command and to perform a write operation in response to a received write command;
• write operation suspend logic configured to receive a command, and to suspend a write operation in response to the command received by the write operation suspend logic;
• read operation logic configured to receive a read command and to perform a read operation in response to a received read command;
• and
• data transfer logic configured to transfer read data of the read operation from the memory;
• wherein the write operation suspend logic is further configured to resume a suspended write operation concurrently with at least a portion of the transfer of read data from the memory.
