The SARAM (sequential access and random access memory), a new kind of dual-port memory for communications now and beyond

As networks have increased in popularity over the past few years, dual-port RAMs have also increased in popularity. This is attributed to the design simplification using the dual-port RAMs. Currently there are many applications requiring the use of dual-port RAMs. One such is the transfer of data between peripherals and controllers in real time to solve high throughput problems. The current design methods use standard static random access memory devices (SRAMs) and first-in-first-out memory devices (FIFOs). In many cases, dual-port RAM devices are the best design solutions to obtain the required throughput bandwidth. A new dual-port RAM, called the SARAM, offers the best of both synchronous and asynchronous interfaces within a single component. In addition, a single SARAM can handle ALL the ATM bus rates up to the current 2.4 Gbps maximum
