摘要:
A current reference, which may be fabricated independently, on a die, as part of an integrated circuit, or a system, or in various other forms, is disclosed. The current reference may include a voltage source having a substantially temperature stable output voltage, a first semiconductor device biased by the substantially temperature stable output voltage to provide a first output current, and a second semiconductor device providing a second output current, wherein a reference current is provided approximately equal to the difference between the first and second output currents.

For a memory cell, where an access transistor couples the memory cell to a local bit line, a pMOSFET essentially eliminates sub-threshold leakage current in the access transistor when the memory cell is not being read, and when the memory cell is being read, an additional pMOSFET essentially eliminates sub-threshold leakage current in the access transistor if the memory cell stores an information bit such that it does not discharge the local bit line. In this way, a half-keeper connected to the local bit line does not need to contend with sub-threshold leakage current.

An electrostatic discharge protection circuit may include ovonic threshold switches that have a holding voltage greater than an input voltage normally received from a pad. As a result, the ovonic threshold switches provide a low resistance state to shunt current from the pad when an electrostatic discharge protection event occurs and, otherwise, present an off device during normal circuit operations.
