The CY62147CV25/30/33 are high-performance CMOS static RAMs organized as 256K words by 16 bits. These devices feature advanced circuit design to provide ultra-low active cur- rent. This is ideal for providing More Battery Life rM (MoBL rM) in portable applications such as cellular telephones. The de- vices also have an automatic power-down feature that signifi-
