IBM Research claims to have fabricated the world's smallest SRAM bit cell with joint industry and university development partners. The SRAM bit cell, which was cast using 22 nanometer design rules, measures just .1 square microns. The SRAM was developed with partners AMD, Freescale, STMicroelectronics, Toshiba and the University of Albany's College of Nanoscale Science and Engineering (CNSE, Albany, N.Y.). The previous world record for the smallest SRAM bit cell was established by IBM in 2004 at .143 square microns in an experimental 32-nm device. Since then, several engineering groups have questioned whether conventional architectures could be extended to the 22-nm node. IBM researchers assert than it can.
