A NAND flash memory logical unit. The NAND flash memory logical unit includes a control circuit that responds to commands and permits program and/or erase commands to be interruptible by read commands. The control circuit includes a set of internal registers for performing the current command, and a set of external registers for receiving commands. The control circuit also includes a set of supplemental registers that allow the NAND flash memory logical unit to have redundancy to properly hold state of an interrupted program or erase command. When the interrupted program or erase command is to resume, the NAND flash memory logical unit thus can quickly resume the paused program or erase operation. This provides significant improvement to read response times in the context of a NAND flash memory logical unit. |
