    • A one-piece fiber optic receptacle is provided for aligning and optically connecting a plug ferrule with a back-side ferrule of like configuration. The fiber optic receptacle includes a receptacle housing defining an internal cavity opening through an external end and an opposed internal end, an alignment sleeve disposed within the internal cavity and received within the internal end of the receptacle housing, and a sleeve retainer secured to the internal end of the receptacle housing and operable for providing access to the alignment sleeve from the internal end of the receptacle housing. The alignment sleeve includes a chamfer for guiding the back-side ferrule into the alignment sleeve. The sleeve retainer has an opening and a plurality of alignment ribs disposed about the opening for permitting angular rotation of the alignment sleeve relative to the sleeve retainer during insertion of the plug ferrule and the back-side ferrule into the alignment sleeve.

    • A first embodiment of a word line voltage boosting circuit for use with an array of non-volatile memory cells has a capacitor, having two ends, connected to the word line. One end of the capacitor is electrically connected to the word line. The other end of the capacitor is electrically connected to a first voltage source. The word line is also connected through a switch to a second source voltage source. A sequencing circuit activates the switch such that the word line is connected to the second voltage source, and the other end of the capacitor is not connected to the first voltage source. Then the sequencing circuit causes the switch to disconnect the word line from the second voltage source, and connect the second end of the capacitor to the first voltage source. The alternate switching of the connection boosts the voltage on the word line. In a second embodiment, a first word line is electrically connected to a first switch to a first voltage source. An adjacent word line, capacitively coupled to the first word line, is electrically connected to a second switch to a second voltage source. A sequencing circuit activates the first switch and the second switch such that the first word line is connected to the first voltage source, and the second word line is disconnected from the second voltage source. Then the sequencing circuit causes the first switch to disconnect the first word line from the first voltage source, and causes the second word line to be electrically connected to the second voltage source. The alternate switching of the connection boosts the voltage on the first word line, caused by its capacitive coupling to the second word line. A boosted voltage on the word line may be used to improve cycling and yield, where the memory cells of the array are of the floating gate type and erase through the mechanism of Fowler-Nordheim tunneling from the floating gate to a control gate which is connected to the word line.
