The Ramtron EDRAM is a 4 Mb dynamic RAM with 2 Kb static RAM cache. It is designed for 35 ns random access times, 15 ns cache cycle times with 5 ns pulse widths and includes logic functions not found on standard DRAM's. The simple solution to testing the part is a 67 to 100 MHz machine, but a more creative solution requires the use of only slightly more creative techniques. The EDRAM, while having its own unique requirements for guaranteeing proper operation, is a part that can be fully tested an standard memory test equipment capable of 30 to 5 MHz operation with an algorithmic pattern generator
