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.
