A non-volatile memory storage device has a non-volatile memory, e.g., a flash memory, and a controller coupled to the non-volatile memory. The controller comprises a plurality of control circuits and an arbitration circuit. Each control circuit is configured to generate a request to update the chip-enable (CE) signals for non-volatile memory, and the arbitration circuit is configured to determine when the requests are acknowledged. The arbitration circuit generates acknowledge signals to the control circuits when all of the requests of the control circuits have been received by the arbitration circuit. The CE signals for non-volatile memory are updated when requests are acknowledged.

Non-volatile memory storage device and operation method thereof

A non-volatile memory device, and a method for accessing the non-volatile memory device are provided. The non-volatile memory device is connected to a host via a bus. The non-volatile memory device comprises an MCU. By independently processing the particular commands using only the auxiliary circuit, the MCU can cease to operate, thus saving power. By setting the bus into power saving mode when the non-volatile memory device is busy, the host and the non-volatile memory device would not communicate mutually, thus, saving power.
