| 1. A semiconductor storage device comprising:
a memory core having memory cells to be accessed; and
an interface circuit having terminals operable to input and output a chip enable signal adapted to select a chip, at least
one control signal adapted to control the chip operation, a clock signal adapted to control the chip I/O operation timing
and a series of data including a command, address and data; wherein
the interface circuit includes at least one input holding unit adapted to hold the control signal, and
the interface circuit processes the control signal after loading it temporarily into the first input holding unit.
