UM6114
Features
• High speed-45/55/70/90 ns (max.)
• Low power dissipation:
50mW (Typ.) operating
5/NV (Typ.) standby
• Single 5V power supply
• Fully static operation
• All inputs and outputs directly TTL compatible
• Three state outputs
• Data retention supply voltage: 2.0-5.5V
General Description
The UM6114 is a 4,096 bit high speed and low power static
random access memory organized as 1,024 words by 4 bits
using CMOS technology, and operates from a single 5-volt
supply.
The UM6114 is compatible with the industry produced
NMOS 2148 type 4K RAM, yet offers a more than 90%
reduction in power of their NMOS equivalents.
The UM6114 is a fully CMOS RAM, therefore it is suited
for use in low power applications where battery operation
and battery back up for nonvolatility are required.
The UM6114 is guaranteed for data retention at a power
supply as low as 2 volts. The UM6114 is directly TTL
compatible in all inputs and outputs.
The UM6114 is offered in both standard 18 pin plastic and
cerdip packages, 0.3 inches in width.

Notes:
1. R/W is High for Read Cycle.
2. Device is continuously selected, CE =VIL.
3. Address valid prior to qr coincident with CE transition low.
4. Transition is measured ±500mV from steady state. This parameter is sampled and not 100% tested.
