Standard SRAM Products

SRAM products are high-speed, reprogrammable, non-volatile memory devices compatible with a range of mobile and embedded applications. SRAM products are based on advanced CMOS technology to provide low power consumption and reliable data retention.

Centennial's patented Rechargeable Card incorporates a Lithium Ion battery and charging circuit that automatically maintains peak condition when in use. The recharge feature eliminates the danger of battery failure and data loss during critical times, the risk of damage to the host and module components when batteries are removed or inserted, and avoids the environmental harm posed when disposing of used batteries. By fully encasing the battery within an ultra-sonically welded housing, Centennial SRAM Recharge Cards offer greater resistance to shock and vibration.
