Abstract

Example reference current distribution circuitry described herein include current mirrors having resistive elements of varying sizes between gate nodes of sense amplifier transistors along a voltage distribution line. Examples of counter coupling capacitances which may be coupled to the gate nodes of sense amplifier transistors are also described.

First claim

What is claimed is:

1. An apparatus, comprising:
a conductive line including a resistance value which varies along a length of the conductive line;
a plurality of sensing circuits coupled to the conductive line, each of the plurality of sensing circuits including a respective sensing transistor and a respective switch coupled to a drain of the respective sensing transistor and wherein the respective switch is configured to switch in accordance with a control signal; and
a capa…
