• Low power operation
• Chip access time: 2.0 /J.s
• Data retention: 2.0V min.
• Three-state outputs
• On-chip address register
• Synchronous circuitry
• Standard 18 pin DIP package
• No clock required (complete static circuit)
General Description
The UM6104-1 is a nonclocked cMos static RAM or-
ganized as 1024 words by 4-bits. Since 1Kx4 CMOS static
RAM is usually used in low voltage or low power consump-
tion situation, such as telephonic equipments and portable
equipments, UMC creates a new product version, UM6104-1
to serve these requirements. UM6104-1 dissif)ates very
little current at the data retention mode and is suitable for
use in non-volatile RAM applications with battery backup.
