Abstract
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.
