ABSTRACT:
A ROM apparatus includes a control circuit for controlling an output buffer to be turned into a high impedance state or an off state for a predetermined time in response to a change of an address signal. For this control circuit, a supply of data read from a wrong address of a memory to an external circuit is prohibited for a duration of a false malfunction which is caused by a precharge of digit lines.
