Ring oscillator for use in memory system, has pair of logic circuits forming two loops such that phase interpolation occurs at node common to loops, where signals from loops mix at another node

摘要

The oscillator has a pair of logic circuits forming two loops such that phase interpolation occurs at a node common to the loops. Signals from the loops mix at a node (A) in which an output signal from a node (C) has traversed two inverting stages for one loop. A node (B) outputs a signal to C and receives an input signal from A. A node (D) receives an output signal from C and provides an input signal to A. Independent claims are also included for the following: (A) a memory method (B) a memory system.
