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 consumption 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.
