Abstract
An input/output buffer circuit is capable of suppressing an increase in current consumption of the whole system even in a low power consumption mode for bringing a clock to a halt. The input/output buffer circuit has an input/output terminal for performing the input/output of data. When a write enable signal WR is in an active state, the input/output buffer circuit outputs a signal to the input/output terminal. When a read enable signal RD is in an active state, the input/output buffer circuit receives data from the input/output terminal. When the write enable signal WR and the read enable signal RD are both in a non-active state, the input/output buffer circuit outputs a signal based on any of signals supplied thereto.
