Abstract
A nonvolatile memory device can include a serial port having at least one serial clock input, and at least one serial data input/output (I/O) configured to receive command, address and write data in synchronism with the at least one serial clock input. At least one parallel port can include a plurality of command address inputs configured to receive command and address data in groups of parallel bits and a plurality of unidirectional data outputs configured to output read data in parallel on rising and falling edges of a data clock signal. Each of a plurality of banks can include nonvolatile memory cells and be configurable for access by the serial port or the parallel port. When a bank is configured for access by the serial port, the bank is not accessible by the at least one parallel port. Related methods and systems are also disclosed.
