A simple 1-transistor capacitor-less memory cell for high performance embedded DRAMs

Abstract

A new compact memory architecture is proposed for embedded dynamic random access memory (eDRAM) cells. By exploiting the floating body effect of partially depleted silicon on insulator (SOI) devices, a one-transistor memory cell can be integrated in a pure logic SOI technology without adding any process step. The data retention, device operation principles and reliability make it ideal for high performance eDRAM applications while reducing the cell area by a factor of two.
