DESCRIPTION
The DS1200 serial RAM chip is a miniature read/write memory that can randomly access individual 8-bit strings (bytes) or sequentially access the entire 1024-bit contents (burst). Interface cost to a microprocessor is minimized by on-chip circuitry, which permits data transfers with only three signals: CLK, RST , and DQ.

FEATURES
◾ 1024 Bits of Read/Write Memory
◾ Low Data Retention Current for Battery Backup Applications
◾ Four Million Bits/Second Data Rate
◾ Single-Byte or Multiple-Byte Data Transfer Capability
◾ No Restrictions on the Number of Write Cycles
◾ Low-Power CMOS Circuitry

APPLICATIONS
◾ Software Authorization
◾ Computer Identification
◾ System Access Control
◾ Secure Personnel Areas
◾ Calibration
◾ Automatic System Setup
◾ Traveling Work Record
