Abstract:
A nonvolatile memory apparatus comprising:a plurality of terminals including a clock terminal, a command terminal and other terminal; a data register; a command register; and a plurality of nonvolatile memory cells, wherein said clock terminal receives a clock signal, wherein said command terminal couples to said command register and receives commands which include a read command and a program command, wherein said data register is used for receiving data from outside of said nonvolatile memory apparatus and is used for outputting data to outside of said nonvolatile memory apparatus, 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 data register, and outputs said read data stored in said data register to outside of said nonvolatile memory apparatus via said other terminal not said command terminal in response to said clock signal, and wherein in an operation in response to said program command, 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 clock signal, stores received data to said data register and writes said received data stored in said data register to ones of said nonvolatile memory cells.
