Noncomplimentary rewriting and serial-data coding scheme forshared-sense-amplifier open-bit-line DRAM

摘要

A noncomplimentary rewriting scheme is proposed for open-bit-linenDRAM's adopting a shared subsense amplifier. The scheme canntheoretically cancel inter-bit-line coupling noise down to zero. Innorder to suppress the peak in unselected word line noise, a serial-datancoding scheme was also developed, This scheme can reduce unselectednword-line noise by at least 50%
