Abstract
A semiconductor storage device comprises a timing control circuit that generates a signal for controlling at least one of a read operation and a write operation; an input-signal pad; a plurality of control-signal pads; and a switch circuit coupled to at least one of the plurality of control-signal pads. The switch circuit generates a first control signal to be supplied to the timing control circuit based on a signal from the input-signal pad in a first mode.
Claims4
A method for manufacturing a semiconductor storage device, the method comprising:
- generating a test control signal based on one of a test command and a test signal;
- generating a first control signal for controlling the semiconductor storage device based on the test control signal and a first signal from an input-signal pad;
- generating a second control signal for controlling the semiconductor storage device based on a second signal from a control-signal pad;
- and
- testing the semiconductor storage device based on the first control signal and the second control signal to manufacture the semiconductor storage device.
