*1 The input signal rise time and fall time (tr, tf) is specified at 15 ns or less. When the system cycle time is extremely fast,
*2 All timing is specified using 20% and 80% of VDD as the reference.
*3 tCCLW and tCCLR are specified as the overlap between CSB being “L” and WR and RD being at the “L” level.
