High-Speed 2K x 9 Dual-Port Static RAM with Busy & Interrupt Industrial and Commercial Temperature Ranges
T iming Waveform of Read Cycle No. 1, Either S ide
(1,2,4)
APRIL 05, 2006
NOTES:
1. Timng depends on which signal is aserted last,
OE
or
CE
.
2. Timng depends on which signal is deaserted first,
OE
or
CE
.
3.
t
BDD
delay is required only in a case where the opposite port is completing a write operation to the same address location. For simultaneous read operations
BUSY
has no relationship to valid output data.
4. Start of valid data depends on which timng becomes effective last,
t
AOE,
t
ACE,
t
AA, or
t
BDD.
5. R/
W
= V
IH
,
CE
= V

, and
OE
= V
IL
, and the address is valid prior to other coincidental with
CE
transition LOW.
