NBT SRAMs

GSI Technology’s No Bus Turnaround (NBT) product portfolio is the largest in the industry with six different densities in x18, 32, 36 and 72 bit widths. Our NBT SRAMs provide the fastest clock rates and lowest power of any in the world.


NBT SRAMs are synchronous, burst-capable memories with a simplified interface that is designed to use a data bus’s maximum bandwidth. NBT devices do not require “turnaround” cycles (idle clock cycles between a read and write operation). NBT SRAMs are used in networking, industrial, automotive and medical imaging applications where a mid-range performance point (typically a 333–166 MHz clock rate) is required.
