RLDRAM II: slightly better than expected
Micron Technology introduced 288Mbit RLDRAM II (reduced latency DRAM) chips that have timings even lower than it was expected. Currently the company is researching these chips at <20ns random access critical for such memory (RLDRAM II is positioned as a comm and storage systems solution.)
Chips work at 400MHz clock speed and provide 800Mbps throughput per pin at tRC=20ns. The 8-bank architecture is optimized for network systems and applications with intense graphics, as the peak bandwidth of 36-bit interface is 28.8Gbps.
Other RLDRAM II advantages includes on-die termination (ODT), multiplexing and non-multiplexing addressing, on-chip delay lock loop (DLL), programmable output impedance and 1.8V.
The new 288Mbit RLDRAM II are shipped in the standard 144-pin FBGA packages sized 11x18.5mm.
