Method and system for communicating with non-volatile memory

A method for communicating with a first flash bank and a second flash bank via a common flash interface, the method comprising a processor of a memory controller:

• in response to receiving a first flash command from a host, determining that the first flash command is intended to be communicated to the first flash bank;
• generating a command sequence from the first flash command, wherein the command sequence is associated with a first priority and comprises two portions, each portion comprising a series of commands, wherein the series of commands is atomic;
• attaching to each portion identification information associated with the first flash bank;
• communicating a first portion of the command sequence to the first flash bank in response to detecting the first priority;
• in response to detecting a command in the series of commands in the first portion, generating an status indication, wherein the status indication indicates that the first portion of the command sequence has been communicated to the first flash bank;
• receiving the indication and determining if another command sequence associated with a second priority and to be communicated to the second flash bank was received;
• comparing the first priority with the second priority in response to determining that the another command sequence was received;
• communicating the second portion of the command sequence to the first flash bank in response to the first priority being greater than the second priority;
• and
• communicating the another command sequence to the second flash bank in response to the second priority being greater than the first priority.

A memory controller for communicating with a first flash bank and a second flash bank, the memory controller comprising:

• a flash interface module configured for communication with the first and second flash banks;
• and
• a processor in communication with the flash interface module, the processor configured to:
• generate a plurality of command sequences in response to receiving a plurality of flash commands from a host system, wherein each of the plurality of command sequences corresponds to a respective one of the plurality of flash commands, wherein some of the plurality of command sequences comprise a first portion and a second portion and each of the first portion and second portion are atomic;
• attach an identifier to each of the first and second portions identifying either the first or the second flash bank;
• associate each of the plurality of command sequences with a priority;
• and
• via the flash interface module, select one of the plurality of the command sequences based on the priority associated with the one of the plurality of the command sequences and transmit sequentially the first portion of the one of the plurality of the command sequences to either one of the first flash bank or the second flash bank.
