<p>PURPOSE:To reduce the power consumption during a writing mode by stopping the internal clock with a writing signal. CONSTITUTION:The clock is produced with an external crystal, and a PROM part is set in a writing mode when a writing signal 1 is set at a high level. The signal 1 turns off a control gate 5 only to the parts excepting the PROM, and therefore no internal clock 6 is sent to the inside of a circuit. As a result, the gate of each circuit is never switched to reduce the power consumption.</p> |
