General Description

The EM42BM3284LBA is Double-Date-Rate Synchronous DRAM fabricated with ultra high performance CMOS process containing 1,073,741,824 bits which organized as 8Meg words x 4 banks by 32 bits.

The 1Gb DDR SDRAM uses a double data rate architecture to accomplish high-speed operation.

The data path internally pre-fetches multiple bits and It transfers the data for both rising and falling edges of the system clock.
