General Description
Simultaneous Read/Write Operations with Zero Latency
S29JL064H Features
The S29JL064H is a 64 megabit, 3.0 volt-only flash memory device, organized as 4,194,304 words of 16 bits
each or 8,388,608 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 48-pin TSOP and 63-ball
Fine Pitch BGA packages. Standard control pins—chip enable (CE#), write enable (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 program and erase operations.
The Simultaneous Read/Write architecture provides simultaneous operation by dividing the memory space
into four banks, two 8 Mb banks with small and large sectors, and two 24 Mb banks of large sectors. Sector
addresses are fixed, system software can be used to form user-defined bank groups.
During an Erase/Program operation, any of the three non-busy banks may be read from. Note that only two
banks can operate simultaneously. The device can improve 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 S29JL064H can be organized as both a top and bottom boot sector configuration.
The Secured Silicon Sector Sector is an extra 256 byte sector capable of being permanently locked by
Spansion or customers. The Secured Silicon Customer Indicator Bit (DQ6) is permanently set to 1 if the part
has been customer locked, and permanently set to 0 if the part has been factory locked. This way, customer
lockable parts can never be used to replace a factory locked part.
Factory locked parts provide several options. The Secured Silicon Sector may store a secure, random 16
byte ESN (Electronic Serial Number), customer code (programmed through Spansion programming
services), or both. Customer Lockable parts may utilize the Secured Silicon 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 allowing 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 structures, 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 physical translation of the data onto the
Flash memory device (or memory devices), and more. Using DMS, user-written software does not need to
interface with the Flash memory directly. Instead, the user's software accesses the Flash memory by calling
one of only six functions.
The device offers complete compatibility with the JEDEC 42.4 single-power-supply Flash command set
standard. Commands are written to the command register using standard microprocessor write timings.
Reading data out of the device is similar to reading from other Flash or EPROM devices.
