A semiconductor storage device comprising:
- an external terminal to which a first signal is supplied;
- a core circuit;
- and
- an access operation control circuit that generates a signal indicating an access operation mode to the core circuit for subsequent cycles based on a pulse width of the first signal.
A semiconductor storage device, wherein the semiconductor storage device is configured to generate a third signal for latching data based on one of a first signal and a second signal to be supplied from an external terminal, to set a first access mode for subsequent cycles based on the first signal, to set a second access mode for the subsequent cycles based on the second signal and to perform an access operation to a core circuit based on one of the first access mode and the second access mode.
A memory system comprising:
- a semiconductor storage device;
- and
- a controller that controls the semiconductor storage device,
- wherein the semiconductor storage device includes:
- a first external terminal to which a first signal is supplied;
- a core circuit;
- and
- an access operation control circuit that generates a signal indicating an access operation mode to the core circuit for subsequent cycles based on a pulse width of the first signal.
