Abstract:
A nonvolatile memory apparatus comprising:a plurality of terminals including a clock terminal, a command terminal and other terminal; a plurality of nonvolatile memory cells; a first volatile memory; and a second volatile memory, wherein said clock terminal receives a first clock signal, wherein said command terminal receives commands which include a read command and a program command, wherein in an operation in response to said read command received from said command terminal, said nonvolatile memory apparatus reads data from ones of said nonvolatile memory cells, stores read data to said second volatile memory, transfers said read data from said second volatile memory to said first volatile memory, and outputs said read data from said first volatile memory to outside of said nonvolatile memory apparatus via said other terminal not said command terminal in response to said first clock signal, and wherein in an operation in response to said program command received from said command terminal, said nonvolatile memory apparatus receives data from outside of said nonvolatile memory apparatus via said other terminal not said command terminal in response to said first clock signal, stores said received data to said first volatile memory, transfers said received data from said first volatile memory to said second volatile memory, and writes said received data from said second volatile memory to ones of said nonvolatile memory cells.
