8-BIT LINE MEMORY (FIFO)
FUNCTION
When write enable input WE is “L”, the contents of data inputs
D
0
to D
7
are written into memory in synchronization with rise
edge of write clock input WCK. At this time, the write address
counter is also incremented simultaneously.
The write function given below are also performed in synchro-
nization with rise edge of WCK.
When WE is “H”, a write operation to memory is inhibited and
the write address counter is stopped.
When write reset input WRES is “L”, the write address counter
is initialized.
When read enable input RE is “L”, the contents of memory are
output to data outputs Q
0
to Q
7
in synchronization with rise
edge of read clock input RCK. At this time, the read address
counter is also incremented simultaneously.
The read functions given below are also performed in syn-
chronization with rise edge of RCK.
When RE is “H”, a read operation from memory is inhibited
and the read address counter is stopped. The outputs are in
the high impedance state.
When read reset input RRES is “L”, the read address counter
is initialized.
