Embodiment Construction

[0014] Certain terms are used throughout the specification and claims that follow to refer to particular elements. Those skilled in the art will appreciate that manufacturers may refer to elements by different names. This document does not intend to distinguish between components with different names but with the same function. In the following descriptions and examples, the terms "comprising" and "including" are used openly, and thus should be read as "including, but not limited to...". Likewise, the term "coupled" is intended to mean an indirect or direct electrical connection. Accordingly, if one device is coupled to another device, that connection may be through a direct electrical connection, or through an indirect electrical connection through other devices and connections.

[0015] The core viewpoint of the present invention is to use the dynamic reference voltage generating unit to generate the dynamic reference voltage for the differential sensing circuit of the sin...

Abstract

The present invention provides a differential sensing circuit with a dynamic voltage reference for a single-ended bit line memory. The exemplary differential sensing circuit comprises: a dynamic voltage reference generating unit and a differential sensing amplifying unit. The dynamic voltage reference generating unit is coupled to an input voltage, and utilized for receiving a setting signal to generate the dynamic voltage reference. The differential sensing amplifying unit is coupled to the single-ended bit line memory and the dynamic voltage reference generating unit, and utilized for receiving at least an input signal from the single-ended bit line memory and the dynamic voltage reference from the dynamic voltage reference generating unit, so as to generate at least an output signal accordingly. The differential sensing circuit with the dynamic voltage reference disclosed by the present invention can improve performance and reduce dynamic power without receiving the DC current and requiring a larger chip area for the single-ended bit line memory, and the differential sensing circuit is suitable for high speed and low power design.

Description

[0001] cross reference [0002] This application claims the benefit of U.S. Provisional Application No. 62 / 092852, filed December 17, 2014, which is incorporated by reference in its entirety. technical field [0003] The disclosed embodiments of the present invention relate to a differential sensing circuit, and more particularly, to a differential sensing circuit with a dynamic reference voltage for a single-ended bit line memory. Background technique [0004] Regarding existing single-ended sensing circuits for single-ended bit line memories, in order to ensure operation avoiding noise, existing single-ended sensing circuits require the bit line to be fully discharged (depending on the trip voltage of the inverter, where the sensing edge value (sense margin) is about 0.5VCC). For this reason, existing single-ended sensing circuits typically give lower readings than differential sensing circuits. Regarding another existing single-ended sensing circuit for single-ended bi...
