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 pipeline stages. Each port

can also be configured to operate in pipeline 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, counter-interrupt (CNTINT) flags to notify that

the counter will reach the maximum value on the next clock

cycle, readback of the burst-counter internal address, mask

retransmit functionality, mailbox interrupt flags for message

passing, JTAG for boundary scan, and asynchronous Master

Reset (MRST). 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 a 256-ball fine

pitch BGA package.
