The LH52258A is a high-speed 262,144 bit static RAM organized as 32K × 8. A fast, efficient design is obtained with a CMOS periphery and a matrix constructed with polysilicon load memory cells. This RAM is fully static in operation. The Chip Enable (E) control permits Read and Write operations when active (LOW) or places the RAM in a low-power standby mode when inactive (HIGH). Standby power (ISB1) drops to its lowest level if E is raised to...
