DATA INPUT/OUTPUT: DQ0~DQ35
data of DQ0 to DQ35 are outputted synchronizing with the both edges of QS output signal.
DATA STROBE: LDS, UDS, LQS, UQS
UQS are for DQ18 to DQ35.
(1) Unidirectional DS / QS mode
(2) Unidirectional DS / Free running QS mode
POWER SUPPLY: V
REFERENCE VOLTAGE: V
The input data of DQ0 to DQ35 are taken in synchronizing with the both edges of DS input signal. The output

Both edges of QS are used for trigger signal of all DQs at Read operation. QS assert always toggle signal
except Self-Refresh mode. This strobe type is easy to use for pin to pin connect application.
