Showing that the worst minimum operating voltage (Vmin) of an 8T dual-port (DP) SRAM is determined by the write/read-disturbing condition with a finite clock skew, we propose a circuit technique to detect the worst Vmin in asynchronous clock operatio

16-Mbit low-power SRAM (SuperSRAM) was developed using a new memory cell technology which makes use of DRAM technology and TFT technology, which has a record of actual performance in SRAM. For SRAM, the problems of soft errors and operation at the lo

The simulation of a thermal-neutron-induced single-event upset (SEU) was performed on a 0.4-µm-design-rule 4 Mbit static random access memory (SRAM) using particle and heavy-ion transport code system (PHITS). The SEU rates obtained by the simulation

With the scaling of MOSFET dimensions and the lowering of supply voltage, more precise estimation of minimum operating voltage (V min ) of SRAM at 6-sigma level is needed. In this paper, we propose a method based on the importance sampling (IS) Monte

We discuss dynamic stability for single-port SRAM that manifests itself in the difference between minimum operating voltage (Vmin) for longer and shorter word-line (WL) pulse width (T wl ). The most probable failure points (MPFPs) that determine Vmin

We propose circuit techniques for an 8T dual-port (DP) SRAM to improve its minimum operating voltage (Vdd min ). Active bitline equalizing technique improves the write margin whenever a write-disturb occurs. This technique is applicable for both sync

Voltage and technology scaling and increasing random variation in MOSFET characteristics reduce the operational margin of SRAM functionality, and several design techniques have been suggested to improve margins [1–3]. However, it is still difficult

In this paper, we propose two kinds of implementations of the dual port MRAM, one of which is for the read/write concurrent operation while another is for the additional simultaneous read operation. Compared with dual port SRAM, the dual port MRAM ac
