IBM Pushes Updated Embedded DRAM

SAN FRANCISCO — Engineers at IBM are preparing another attack on SRAM territory with an improved embedded DRAM (eDRAM) technology intended to make ASIC and high-performance processor designers take another look at the sometimes controversial technology.
IBM introduced a 144-Mbit DRAM on Wednesday (Feb. 12) with a cycle time of 5.6 nanoseconds, a data rate of 1.4 Gbits/second per pin and a die size of 121 mm2. The company asserted that its new architecture enables the DRAM's I/O bandwidth to compete with high-performance SRAMs, yet with an eightfold density improvement over its SRAM predecessors at IBM. Consequently, IBM's memory evangelists are predicting an increase in the instances where embedded DRAM replaces conventional SRAM, especially in high-performance processors such as Intel Corp.'s Itanium line.
