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.

 

Features

  • NBT functionality allows zero wait read-write-read bus utilization
  • Fully pin-compatible NtRAM™, NoBL™, and ZBT™ SRAMs
  • LBO pin for Linear or Interleaved Burst mode
  • Byte Write (BW) and/or Global Write (GW) operation
  • Internal self-timed write cycle
  • Automatic power-down for portable applications
  • JEDEC-standard pinout and package
  • RoHS-compliant package available
