FUNCTION TRUTH TABLE
Asynchronous Operation (Page Mode)
Note:
L = V
IL
, H = V
IH
, X can be either V
IL
or V
IH
, High-Z = High Impedance
*1: Should not be kept this logic condition longer than 1ms.
Please contact local FUJITSU representative for the relaxation of 1ms 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: "L" for address pass through and "H" for address latch on the rising edge of ADV#.
*4: OE# can be V
IL
during Write operation if the following conditions are satisfied;
(1) Write pulse is initiated by CE#1 (refer to CE#1 Controlled Write timing), or
cycle time of the previous operation cycle is satisfied.
(2) OE# stays V
IL
during Write cycle.
*5: Can be either V
IL
or V
IH
but must be valid before Read or Write.
*6: Output is either Valid or High-Z depending on the level of UB# and LB# input.
