WebFeb 5, 2024 · SRAM holds a bit of data on 4 transistors with using of 2 cross coupled inverters, and it has two stable states like as 0 and 1. Due to read and write operations, other two access transistors are used to handle the availability for memory cell.It needs 6 MOFSET (metal-oxide-semiconductor field-effect transistor) to hold per memory bit. Web1 day ago · In addition, we have used the NDR diode to build the SRAM cell and demonstrate, write, and read operations. The NDR-OSRAM operates using a low-supply voltage of less than 2 V and is fabricated using the standard silicon on insulator (SOI) CMOS process, making it a useful building block for optical computation.
