High-Z = High Impedance
*1: Should not be kept this logic condition longer than 4ms.
Please contact local FUJITSU representative for the relaxation of 4ms limitation.
*2: Power Down mode can be entered from Standby state and all DQ pins are in High-Z state.
Data retention depends on the selection of Partial Size.
Refer to "Power Down" in FUNCTIONAL DESCRIPTION for the details.
*3: Valid clock edge shall be set on either positive or negative edge through CR Set. CLK must be started and
stable prior to memory access.
*4: Can be either V
IL
or V
IH
except for the case the both of OE# and WE# are V
IL
. It is prohibited to bring the
both of OE# and WE# to V
IL
*5: When device is operating in "WE# Single Clock Pulse Control" mode, WE# is don’t care once write operation
is determined by WE# Low Pulse at the beginnig of write access together with address latching. Write
suspend feature is not supported in "WE# Single Clock Pulse Control" mode
*6: Can be either V
IL
or V
IH
but must be valid before Read or Write is determined. And once UB# and LB#
inputs are determined, they must not be changed until the end of burst.
*7: Once valid address is determined, input address must not be changed during ADV#=L.
*8: If OE#=L, output is either Invalid or High-Z depending on the level of UB# and LB# input. If WE#=L,
Input is Invalid. If OE#=WE#=H, output is High-Z.
*9: Output is either Valid or High-Z depending on the level of UB# and LB# input.
*10: Input is either Valid or Invalid depending on the level of UB# and LB# input.
*11: Output is either High-Z or Invalid depending on the level of OE# and WE# input.
*12: Keep the level from previous cycle except for suspending on last data. Refere to "WAIT# Output Function"
in FUNCTIONAL DESCRIPTION for the details.
*13: WAIT# output is driven in High level during write operation.
