Data storage device which serializes memory device ready/busy signals

摘要

A data storage device may include a command bus, a status bus, multiple memory devices that are operably coupled to the command bus and to the status bus, and a controller including multiple channel controllers, where the channel controllers are operably coupled to the command bus and to the status bus and each of the channel controllers is arranged and configured to control one or more of the memory devices. The data storage device may include multiple programmable logic devices that are operably coupled to the status bus, where each of the programmable logic devices is configured to retrieve a ready/busy signal from each of the memory devices under control of one of the channel controllers using the status bus, serialize the ready/busy signals and communicate the serialized ready/busy signals to the channel controllers.
