چکیده

This paper presents a proposed NMOS-centered 6T SRAM cell layout that reduces a neutron-induced multiple-cell-upset (MCU) SER on a same wordline. We implemented an 1-Mb SRAM macro in a 65-nm CMOS process and irradiated neutrons as a neutron-accelerated test to evaluate the MCU SER. The proposed 6T SRAM macro improves the horizontal MCU SER by 67–98% compared with a general macro that has PMOS-centered 6T SRAM cells. key words: SRAM, soft error rate (SER), multiple cell upset (MCU), neutron particle, twin well, triple well

Soft-Error Resilient and Margin-Enhanced N-P Reversed 6T SRAM Bitcell

This paper describes a soft-error tolerant and marginenhanced nMOS-pMOS reversed 6T SRAM cell. The 6T SRAM bitcell comprises pMOS access and driver transistors, and nMOS load transistors. Therefore, the nMOS and pMOS masks are reversed in comparison with those of a conventional bitcell. In scaled process technology, The pMOS transistors present advantages of small random dopant fluctuation, str...

Energy-Efficient SRAM Design in 28nm FDSOI

As CMOS scaling continues to sub-32nm regime, the effects of device variations become more prominent. This is very critical in SRAMs, which use very small transistor dimensions to achieve high memory density. The conventional 6T SRAM bit-cell, which provides the smallest cell-area, fails to operate at lower supply voltages (Vdd). This is due to the significant degradation of functional margins ...

A novel two-port 6T CMOS SRAM cell structure for low-voltage VLSI SRAM with single-bit-line simultaneous read-and-write access (SBLSRWA) capability

This paper reports a two-port 6T CMOS SRAM cell structure for low-voltage VLSI SRAM with single-bit-line simultaneous read-and-write access (SBLSRWA) capability. With a unique structure by connecting the source terminal of an NMOS device in the SRAM cell to the write word line, this SRAM cell can be used to provide SBLSRWA capability for 1V two-port VLSI SRAM as verified by SPICE results.

Analysis of Leakage Current and SNM For 7T SRAM Cell in Nanometre Era

: In the microprocessors world SRAM play a vital role, but as the technology is scaling in nanometer, leakage current and leakage power both are the most known problems for SRAM cells in low power applications. More than 40% of the total power of the SRAM is waste due to the leakage through transistor. This paper compares the working, performance and results of two different SRAM topologies; a ...
