Experimental Evaluation of a Low-Power Sense Comparator for Multilevel Flash Memories
نویسندگان
چکیده
This paper presents the experimental evaluation of a fully-differential offset-compensated voltage comparator designed for use in multilevel (ML) Flash memory sensing. The comparator is made up by an input buffering stage followed by a gain stage that performs a regenerative action. The circuit has been integrated in a 0.13-μm triple-well Flash CMOS process. The experimental evaluation showed an overall comparison time within 35 ns (input signal 10 mV) with a current consumption of ~15 μA from the highvoltage supply. These results make the proposed solution well suited to ML sensing. Key-Words: Flash memories, multilevel, sensing, sense amplifier, comparator

Circuit Techniques for 1.5-V Power Supply Flash Memory
We describe circuit techniques for a Flash memory which operates with a VDD of 1.5 V. For the interface between the peripheral circuits and the memory core circuits, two types of level shifter circuits are proposed which convert a VDD level signal into the high voltage signals needed for high performance. In order to improve the read performance at a low VDD , a new self-bias bitline voltage se...

A 2.5 GS/s flash ADC, fabricated in 90nm CMOS utilizes comparator redundancy to avoid traditional power, speed and accuracy trade-offs. The redundancy removes the need to control comparator offsets, allowing the large process-variation induced mismatch of small devices in nanometer technologies. This enables the use of small-sized, ultra-low-power comparators with clock-gating capabilities in o...

The analog-to-digital converter (ADC) is an essential part of system-on-chip (SoC) products because it bridges the gap between the analog physical world and the digital logical world. In the digital domain, low power and low voltage requirements are becoming more important issues as the channel length of MOSFET shrinks below 0.25 sub-micron values. Moreover, SoC trends force ADCs to be integrat...
