This work compares eight different dynamic and static memory cell designs, embedded in identical memory architectures in a nanometer CMOS process typically adopted for QC cryo-CMOS interfaces
Power consumption is a critical consideration in the design of memory elements and digital systems within very large scale integration (VLSI) circuits. This study introduces a method for reducing power consumption in DRAM sense amplifiers, termed FSPA-VLSA (Foot Switch PMOS Access Voltage Latch Type Sense Amplifier). By implementing this technique within the open bit architecture of DRAM Cells during read operations, an approximate 81% reduction in overall power consumption has been achieved. Additionally, this proposed circuit offers advantages for low-power VLSI/ULSI design. The circuit has been successfully designed and implemented using Cadence Virtuoso tools at 45nm technology.
