Abstract
The decoded-source sense amplifier (DSSA) for high-speed, high-density DRAMs is discussed. To prevent clamping of the common-source node of the sense amplifier caused by bit-line discharge current, the DSSA has an additional latching transistor with a gate controlled by a column decoder. The DSSA has been successfully installed in a 4-Mb DRAM and provided a RAS access time of 60 ns under a V/sub cc/ of 4 V at 85 degrees C. >
