SRAM for IoT Applications in 0.6um CMOS

Abstract

This article presents the detailed design and implementation of a Static Random-Access Memory (SRAM) in CMOS technology. The data access (read/write) is done through Serial Peripheral Interface (SPI), an industry-standard serial protocol. This SRAM is specifically suitable for Internet-of-Things (IoT) applications with slow access rates and low power consumption. For the purpose of demonstration, a 32-byte SRAM was designed and fabricated in 0.6um CMOS technology and successfully tested for its full functionality after fabrication.
