White Electronics Designs Corp. has released what it claims to be the industry's first 72Mb No Bus Latency (NoBL) SSRAM and is offered in speeds of 150MHz to 225MHz, making them suitable for use in data and telecommunications equipment such as terabit edge switches, routers, and GbE switches.

The 2.5V device features a 2Mx36 configuration and is fully-compatible with the company's ZBT device architecture. It is claimed to sustain 100 percent duty cycle by eliminating the turnaround cycle when transition occurs between functional modes of R/W or W/R operations.

All inputs to the device, except the asynchronous output enable, are synchronized to the rising edge of the input clock and write operations are internally self-timed. This feature eliminates off-chip write pulse generation and provides increased timing flexibility, as well as array efficiency.

The device is packaged in a 14-by-22mm, 119 BGA and priced at $240 each in volumes of 1,000 pieces.
