Functional Description
The CYDC128B16 is a low power complementary metal oxide
semiconductor (CMOS) 4K, 8K,16K × 16, and 8/16K × 8
dual-port static RAM. Arbitration schemes are included on the
devices to handle situations when multiple processors access
the same piece of data. Two ports are provided, permitting
independent, asynchronous access for reads and writes to any
location in memory. The devices can be used as standalone
16-bit dual-port static RAMs or multiple devices can be combined
in order to function as a 32-bit or wider master/slave dual-port
static RAM. An M/S pin is provided for implementing 32-bit or
wider memory applications without the need for separate master
and slave devices or additional discrete logic. Application areas
include interprocessor/multiprocessor designs, communications
status buffering, and dual-port video/graphics memory.
Each port has independent control pins: Chip Enable (CE), Read
or Write Enable (R/W), and Output Enable (OE). Two flags are
provided on each port (BUSY and INT). BUSY signals that the
port is trying to access the same location currently being
accessed by the other port. The interrupt flag (INT) permits
communication between ports or systems by means of a mail
box. The semaphores are used to pass a flag, or token, from one
port to the other to indicate that a shared resource is in use. The
semaphore logic is comprised of eight shared latches. Only one
side can control the latch (semaphore) at any time. Control of a
semaphore indicates that a shared resource is in use. An
automatic power down feature is controlled independently on
each port by a Chip Enable (CE) pin.
The CYDC128B16 are available in 100-pin TQFP packages.
