Simultaneous Read/Write Operations with Zero Latency
S29JL032H Features
The S29JL032H is a 32 megabit, 3.0 volt-only flash memory device, organized as
2,097,152 words of 16 bits each or 4,194,304 bytes of 8 bits each. Word mode
data appears on DQ15–DQ0; byte mode data appears on DQ7–DQ0. The device
is designed to be programmed in-system with the standard 3.0 volt V
and can also be programmed in standard EPROM programmers.
The device is available with an access time of 55, 60, 70, or 90 ns and is offered
in a 48-pin TSOP package. Standard control pins—chip enable (CE#), write en-
able (WE#), and output enable (OE#)—control normal read and write operations,
and avoid bus contention issues.
The device requires only a single 3.0 volt power supply for both read and write
functions. Internally generated and regulated voltages are provided for the pro-
gram and erase operations.
The Simultaneous Read/Write architecture provides simultaneous operation
by dividing the memory space into separate banks (see Table 2). Sector ad-
dresses are fixed, system software can be used to form user-defined bank
groups.
During an Erase/Program operation, any of the non-busy banks may be read
from. Note that only two banks can operate simultaneously. The device can im-
prove overall system performance by allowing a host system to program or erase
in one bank, then immediately and simultaneously read from the other bank, with
zero latency. This releases the system from waiting for the completion of program
or erase operations.
The S29JL032H can be organized as both a top and bottom boot sector
configuration.
The SecSi™ (Secured Silicon) Sector is an extra 256 byte sector capable of
being permanently locked by FASL or customers. The SecSi Customer Indicator
Bit (DQ6) is permanently set to 1 if the part has been customer locked, perma-
nently set to 0 if the part has been factory locked, and is 0 if customer lockable.
This way, customer lockable parts can never be used to replace a factory locked
part.
Factory locked parts provide several options. The SecSi Sector may store a se-
cure, random 16 byte ESN (Electronic Serial Number), customer code
(programmed through Spansion programming services), or both. Customer Lock-
able parts may utilize the SecSi Sector as bonus space, reading and writing like
any other flash sector, or may permanently lock their own code there.
DMS (Data Management Software) allows systems to easily take advantage
of the advanced architecture of the simultaneous read/write product line by al-
lowing removal of EEPROM devices. DMS will also allow the system software to
be simplified, as it will perform all functions necessary to modify data in file struc-
tures, as opposed to single-byte modifications. To write or update a particular
piece of data (a phone number or configuration data, for example), the user only
needs to state which piece of data is to be updated, and where the updated data
is located in the system. This is an advantage compared to systems where user-
written software must keep track of the old data location, status, logical to phys-
ical translation of the data onto the Flash memory device (or memory devices),
