Abstract

The invention discloses an integrated circuit, a memory device, and a method of managing a bit line voltage generation circuit, in which the integrated circuit provides a stable clamping voltage to atleast one bit line connected to a memory cell of the memory device. The integrated circuit comprises an operational amplifier for receiving a first reference voltage, a feedback voltage and a compensation current and outputting an output voltage; and an output transistor providing an endpoint voltage as a feedback voltage and an output voltage, where the output voltage is a target voltage relatedto the clamping voltage. The operational amplifier is configured to be unbalanced, and the endpoint voltage of the operational amplifier is smaller than the first reference voltage. And the compensation current compensates the operational amplifier, so that the clamping voltage is substantially constant and independent of the PVT (process voltage temperature) effect.

Description

technical field [0001] The present invention relates to an integrated circuit, a memory device and a method of managing a bit line voltage generating circuit, and more particularly to a system, a method, a computer readable medium for managing a bit line voltage generating circuit of a memory device, circuits and devices. Background technique [0002] Integrated circuit memory devices are becoming smaller and faster. The size and speed limitations of memory devices are caused by the circuitry used to provide a stable bit line clamping voltage to sense data from the memory device. A bit line voltage generating circuit is generally used to maintain a bit line of a memory cell of a memory at a stable clamping voltage. In some cases, a bandgap buffer is used between the bandgap reference system and the bit line voltage generation circuit to convert the bandgap reference voltage from the bandgap reference system into a relatively low voltage, which in turn generates the bit li...
