Clock synchronized nonvolatile memory device

A nonvolatile memory apparatus comprising:

• a control circuit;
• a plurality of terminals including a first terminal, a second terminal and an other terminal;
• and
• a nonvolatile memory array including a plurality of nonvolatile memory cells,
• wherein said first terminal is capable of receiving a clock signal,
• wherein said second terminal is capable of receiving information for specifying arbitrarily any one of operations which include a read operation and a program operation,
• wherein each of said nonvolatile memory cells is capable of storing multi bit type data being more than two bits,
• wherein said control circuit executes operation steps corresponding to specified operation read out from a program memory,
• wherein in said read operation, said control circuit controls, based on operation steps corresponding to said read operation, reading of multi bit type data from ones of said nonvolatile memory cells, converting multi bit type data to binary type data, and outputting binary type data via said other terminal except said command terminal in response to said clock signal, and
• wherein in said program operation, said control circuit controls, based on operation steps corresponding to said program operation, receiving of binary type data via said other terminal except said command terminal in response to said clock signal, converting binary type data to multi bit type data, and writing multi bit type data to ones of said nonvolatile memory cells.
