Alliance Semiconductor Adds 9-Mb Synchronous Dual-Port Family to Memory Portfolio
Devices Speed Inter-Processor Communications, Simplify Systems
Design and Enable Significant System Cost Savings
SANTA CLARA, Calif.—(BUSINESS WIRE)—Sept. 28, 2004—
Alliance Semiconductor Corporation (Nasdaq:ALSC), a worldwide
provider of analog and mixed signal products, high-performance memory
products and connectivity and networking solutions for the
communications, computing, embedded, industrial and consumer markets,
today announced the availability of its 9-Mb synchronous dual-port
family of devices. The Alliance 9-Mb synchronous devices operate at
200MHz making them suitable for high-performance designs that require
shared memory devices such as wireless base stations, network switches
and routers, as well as other networking, storage and RAID
applications. These devices represent the first member of a growing
family of dual-port memory from Alliance.
Alliance's 9-Mb synchronous dual-port family is currently
available in two configurations: 256K x 36 bits and 512K x 18 bits.
Designed specifically to optimize and streamline the
intercommunication and message passing between processors (CPUs) or
digital signal processors (DSPs) within a system, by allowing the CPUs
or the DSPs to simultaneously read and write from both ports. They are
able to sustain an aggregate bandwidth of 14 Gbps to meet the
bandwidth and performance requirements of most systems. In addition,
these devices give systems designers the option to eliminate the need
for multiple standard memories in an application, thereby lowering
design complexity, board space and cost while increasing system
reliability.
"The introduction of our 9-Mb synchronous dual-port family is yet
another proof point of our continuing commitment to solving our
customers' complex design needs, and underscores our efforts in
providing industry leading solutions," said Robert Napaa, vice
president of marketing for Alliance. "We have developed a family of
devices that offers a host of features enabling CPUs or DSPs to
effectively exchange data. With our capabilities and outstanding
design team, Alliance is strongly positioned to deliver next
generation specialty and multi-port memory solutions more quickly and
cost effectively."
The Alliance 9-Mb synchronous dual-port family is based on true
dual-port memory cells that allow the simultaneous access of any
address location within the array from both ports. The device family
incorporates a selectable Flow-Through or Pipeline output feature to
provide flexibility in system design. Both the 256K and 512K devices
operate at the industry's current highest clock rate of 200MHz with a
clock-to-data valid time of 3.4ns. A special collision mechanism is
built into the array to alert the user of a possible collision when a
port is writing to a certain location while the other port is reading
from the same location.
The dual-port device's IO supply voltage can be set independently
on each port to either 3.3V or 2.5V to function as voltage bus
matching between two separate voltage domains. All of the voltage
options are pin-compatible with one another, giving designers the
necessary functionality to support highly modular devices that
ultimately minimizing design cycles and shortening time-to-market
while maximizing return on investment.
The Alliance 9-Mb synchronous dual-port family is currently
available in a 256-pin Ball Grid Array (BGA) package. The devices will
also be made available in other package options including 208-pin fine
pitch Ball Grid Array (fpBGA) and 208-pin Plastic Quad Flatpack
(PQFP). The dual-port devices are also available in lead-free and
environmentally safe green package options.
The complete family of Alliance's 9-Mb synchronous dual-port
devices are currently sampling with production quantity available at
the end of 2004. For more information regarding the 9-Mb dual-port
