The IDT7014 is a high-speed 4K x 9 Dual-Port Static RAM designed
to be used in systems where on-chip hardware port arbitration is not
needed. This part lends itself to high-speed applications which do not rely
on BUSY signals to manage simultaneous access.
The IDT7014 provides two independent ports with separate control,
address, and I/O pins that permit independent, asynchronous access for
reads or writes to any location in memory. See functional description.
The IDT7014 utilitizes a 9-bit wide data path to allow for parity at the
user's option. This feature is especially useful in data communication
applications where it is necessary to use a parity bit for transmission/
reception error checking.
Fabricated using a high-performance technology, these Dual-Ports
typically operate on only 750mW of power at maximum access times as
fast as 12ns.
The IDT7014 is packaged in a 52-pin PLCC and a 64-pin thin quad
flatpack, (TQFP).
True Dual-Ported memory cells which allow simultaneous
reads of the same memory location

NOTES:
1. Transition is measured 0mV from Low or High-impedance voltage with Output Test Load (Figure 2).
2. This parameter is guaranteed by device characterization, but is not production tested.
3. The specification for tDH must be met by the device supplying write data to the RAM under all operating conditions. Although tDH and tOW values will vary over voltage
and temperature, the actual tDH will always be smaller than the actual tOW.
4. Port-to-port delay through RAM cells from writing port to reading port, refer to “Timing Waveform of Write With Port-to-Port Read”.

NOTES:
1. R/W must be HIGH during all address transitions.
2. tWR is measured from R/W going HIGH to the end of write cycle.
3. During this period, the I/O pins are in the output state, and input signals must not be applied.
4. Transition is measured 0mV from the Low or High-impedance voltage with the Output Test Load (Figure 2).
5. If OE is LOW during a R/W controlled write cycle, the write pulse width must be the larger of tWP or (tWZ + tDW) to allow the I/O drivers to turn off data to be
placed on the bus for the required tDW. If OE is HIGH during an R/W controlled write cycle, this requirement does not apply and the write pulse can be as short as
the specified tWP.
Truth Table I – Read/Write Control
Functional Description
The IDT7014 provides two ports with separate control, address,
and I/O pins that permit independent access for reads or writes to
any location in memory. It lacks the chip enable feature of CMOS Dual
Ports, thus it operates in active mode as soon as power is applied. Each
port has its own Output Enable control (OE). In the read mode, the port’s
OE turns on the output drivers when set LOW. The user application should
avoid simultaneous write operations to the same memory location. There
is no on-chip arbitration circuitry to resolve write priority and partial data
from both ports may be written. READ/WRITE conditions are illustrated
in Table 1.
