<p>PURPOSE:To prevent a first-in first-out (FIFO) memory from being delayed in a start and a reset time, by designating a part of memory cell groups including address 0 as a static memory. CONSTITUTION:As for the FIFO memory, addresses from an address 0 to an address (a) are constituted of static memories 1, and residual addresses after an address (a+1), of cell groups of dynamic cells 2 and 3. Therefore, in a reset time from an optional address, a signal is read and outputted instantly from a cell 1, and in the preceding read time, a preparation for the address (a+1), etc., is completed, and an access delay due to the dynamic cell in case of selecting, in prevented. As a result, the delay in the start and reset time can be prevented, and the fast and large capacity of memory can be realized.</p> |
