Inf o rmation
Refer to Table 32 for timing specifications and to Figure 16 for the timing diagram. ICC1 in the DC
Characteristics table represents the active current specification for reading array data.
Random Read (Non-Page Read)
Address access time (tACC) is equal to the delay from stable addresses to valid output data. The
chip enable access time (tCE) is the delay from the stable addresses and stable CE# to valid data
at the output inputs. The output enable access time is the delay from the falling edge of the OE#
to valid data at the output inputs (assuming the addresses have been stable for at least tACC–tOE
time).
Page Mode Read
The device is capable of fast page mode read and is compatible with the page mode Mask ROM
read operation. This mode provides faster read access speed for random locations within a page.
Address bits Amax–A3 select an 8 word page, and address bits A2–A0 select a specific word
within that page. This is an asynchronous operation with the microprocessor supplying the spe-
cific word location.
The random or initial page access is tACC or tCE and subsequent page read accesses (as long as
the locations specified by the microprocessor falls within that page) is equivalent to tPACC. When
CE# (CE1# and CE#2 in PL129J) is deasserted (=VIH), the reassertion of CE# (CE1# or CE#2
in PL129J) for subsequent access has access time of tACC or tCE. Here again, CE# (CE1# /CE#2
in PL129J)selects the device and OE# is the output control and should be used to gate data to
the output inputs if the device is selected. Fast page mode accesses are obtained by keeping
Amax–A3 constant and changing A2–A0 to select the specific word within that page.
Simultaneous Read/Write Operation
In addition to the conventional features (read, program, erase-suspend read, erase-suspend
program, and program-suspend read), the device is capable of reading data from one bank of
memory while a program or erase operation is in progress in another bank of memory (simulta-
neous operation). The bank can be selected by bank addresses (PL127J: A22–A20, PL129J and
PL064J: A21–A19, PL032J: A20–A18) with zero latency.
The simultaneous operation can execute multi-function mode in the same bank.
