Abstract

A write driver for PCM is designed to improve reliability and bit yield in the write operation, due to the distributions during the phase change process. And the PCM cell can be injected by current or voltage respectively. Meanwhile, owing to the possible variations of the SET process parameters, the designed circuit can generate either multiple stepdown current pulse or multiple step-down voltage pulse. The circuit is developed based on SMIC 130 nm CMOS standard technology. Compared to the traditional constant current pulse programming, the test results show that the proposed multiple step-down current generator for SET operation can improve the uniformity of resistance and bit yield.
