pSRAM AC CHARACTERISTICS
Read Cycle
Notes:
1. WE# = V
IH
.
2. t
HZ
and t
OHZ
are defined as the time at which the outputs achieve the open circuit conditions and are not referenced to output
voltage levels.
3. At any given temperature and voltage condition, t
HZ
(Max.) is less than t
LZ
(Min.) both for a given device and from device to device
interconnection.
4. Do not access device with cycle timing shorter than t
RC
for continuous periods < 10 μs.
