A 16-kb 9T Ultralow-Voltage SRAM With Column-Based Split Cell-VSS, Data-Aware Write-Assist, and Enhanced Read Sensing Margin in 28-nm FDSOI

This work proposes an static random access memory (SRAM) with column-based split cell-VSS (CS-CVSS), data-aware write-assist (DAWA), and enhanced read sensing margin in 28-nm FDSOI technology. The proposed CS-CVSS and DAWA techniques improve both half-selected (HS) static noise margin (SNM) and write margin. They also improve HS dynamic noise margin (HS-DNM) by leveraging write through virtual gro...
