Abstract

The need for high accuracy, low power consumption, and compact design has increased because of the quick developments in NAND flash memory technology. Conventional sensing techniques, such the Offset Cancelling Sensing Latch (OCSL), have significant drawbacks that impair performance and efficiency, such as excessive energy consumption from short-circuit currents and noise sensitivity. The proposed method reduces the danger of short circuits and noise sensitivity by substituting a Variable Threshold Detector (VTD) for traditional tri-state sensing latches. VTD improves accuracy while using less energy during the sampling phase by dynamically modifying the sensing threshold voltage (VTRIP). By adjusting the threshold voltage, the VTD maximizes power dissipation, reducing power dissipation by 22.8% and increasing power efficiency by 18.6%, in contrast to conventional OCTSL systems that pre-charge sensor nodes to VDD. Furthermore, by removing DC regulators and coupling capacitors, the adaptive threshold adjustment can be done. Faster and more power-efficient sensing operations are ensured by transmission gates integrated at the sensing latch. Tanner EDA tools are used to implement the design, confirming notable performance gains over traditional methods.
