Functional Description
The FullFlex™ Dual-Port SRAM families consist of 4-Mbit,
9-Mbit, 18-Mbit, and 36-Mbit synchronous, true dual-port static
RAMs that are high-speed, low-power 1.8V/1.5V CMOS. Two
ports are provided, allowing the array to be accessed simulta-
neously. Simultaneous access to a location triggers determin-
istic access control. For FullFlex72 these ports can operate
independently with 72-bit bus widths and each port can be
independently configured for two pipelined stages. Each port
can also be configured to operate in pipelined or flow-through
mode.
Advanced features include built-in deterministic access
control to manage address collisions during simultaneous
access to the same memory location, Variable Impedance
Matching (VIM) to improve data transmission by matching the
output driver impedance to the line impedance, and echo
clocks to improve data transfer.
To reduce the static power consumption, chip enables can be
used to power down the internal circuitry. The number of
cycles of latency before a change in CE0 or CE1 will enable
or disable the databus matches the number of cycles of read
latency selected for the device. In order for a valid write or read
to occur, both chip enable inputs on a port must be active.
Each port contains an optional burst counter on the input
address register. After externally loading the counter with the
initial address, the counter will increment the address inter-
nally.
Additional features of this device include a mask register and
a mirror register to control counter increments and
wrap-around. The counter-interrupt (CNTINT) flags notify the
host that the counter will reach maximum count value on the
next clock cycle. The host can read the burst-counter internal
address, mask register address, and busy address on the
address lines. The host can also load the counter with the
address stored in the mirror register by utilizing the retransmit
functionality. Mailbox interrupt flags can be used for message
passing, and JTAG boundary scan and asynchronous Master
Reset (MRST) are also available. The logic block diagram in
Figure 1
displays these features.
The FullFlex72 is offered in a 484-ball plastic BGA package.
The FullFlex36 and FullFlex18 are offered in both 484-ball and
256-ball fine pitch BGA packages.
