The PDM4M4050 is a 256K x 32 static RAM module constructed on an epoxy laminate (FR-4) substrate using eight 256K x 4 static RAMs in plastic SOJ packages. Availability of four chips select lines (one for each group of two RAMs) provides byte access. Extremely fast speeds can be achieved due to the use of 1 megabit static RAMs fabricated in Paradigm's high-performance, high-reliability technology. The PDM4M4050 is available with access time as fast as 10 ns with minimal power consumption.
