Simultaneous Read/Write Operations with Zero Latency
S29JL032H Features
The Simultaneous Read/Write architecture provides simultaneous operation by dividing the memory space
into separate banks (see
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 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 S29JL032H can be organized as both a top and bottom boot sector configuration.
The Secured Silicon Sector is an extra 256 byte sector capable of being permanently locked by the
customer. The Secured Silicon Customer Indicator Bit (DQ6) is permanently set to 1 if the part has been
locked and is 0 if lockable.
Customers 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.
The host system can detect whether a program or erase operation is complete by using the device status
bits: RY/BY# pin, DQ7 (Data# Polling) and DQ6/DQ2 (toggle bits). After a program or erase cycle has been
completed, the device automatically returns to the read mode.
The sector erase architecture allows memory sectors to be erased and reprogrammed without affecting the
data contents of other sectors. The device is fully erased when shipped from the factory.
Hardware data protection measures include a low V
during power transitions. The hardware sector protection feature disables both program and erase
operations in any combination of the sectors of memory. This can be achieved in-system or via programming
equipment.
The device offers two power-saving features. When addresses have been stable for a specified amount of
time, the device enters the automatic sleep mode. The system can also place the device into the standby
mode. Power consumption is greatly reduced in both modes.
