PSRAM AC CHARACTERISTICS
Read Operation
Notes:
1. Maximum value is applicable if CE1# is kept at Low
without change of address input of A3 to A20.
2. Address should not be changed within minimum t
RC.
3. The output load 50pF.
4. The output load 5pF.
5. Applicable to A3 to A20 when CE1# is kept at Low.
6. Applicable only to A0, A1 and A2 when CE1# is kept at Low
for the page address access.
7. In case Page Read Cycle is continued with keeping CE1#
stays Low, CE1# must be brought to High within 4
μ
s. In
other words, Page Read Cycle must be closed within 4
μ
s.
8. Applicable when at least two of address inputs among
applicable are switched from previous state.
9. t
RC
(min) and t
PRC
(min) must be satisfied.
