Product Summary
The MT49H16M36FM-25E:A is a 288Mb reduced latency DRAM (RLDRAM) II designed for high bandwidth communication data storage. Applications include, but are not limited to, transmitting or receiving buffers in telecommunication systems and data or instruction cache applications requiring large amounts of memory. The MT49H16M36FM-25E:A’s eightbank architecture is optimized for high speed and achieves a peak bandwidth of 28.8 Gb/s, using two separate 18-bit double data rate (DDR) parts and a maximum system clock of 400 MHz.
