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 acplish 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.

Key Features

  • Internal Double-Date-Rate architecture with 2 Accesses per clock cycle.
  • 1.8V ±0.1V VDD/VDDQ.
  • 1.8V LV-COMS compatible I/O.
  • Burst Length (B/L) of 2, 4, 8, 16.
  • 3 Clock read latency.
  • Bi-directional,intermittent data strobe(DQS).
  • All inputs except data and DM are sampled at the positive edge of the system clock.
  • Data Mask (DM) for write data.
  • Sequential & Interleaved Burst type available.
  • Auto Precharge optio.
