High Speed Differential ROM - A simplified explanation of the abstract

This abstract first appeared for US patent application 18667059 titled 'High Speed Differential ROM

Simplified Explanation:

This semiconductor device includes a ROM, a differential sense amplifier, and a multiplexer logic circuit. The ROM has memory cells arranged in rows along word lines and columns along bit lines, with a reference column containing reference transistors along a reference bit line. The multiplexer logic circuit connects a selected bit line to a first differential amplifier input and the reference bit line to the second differential amplifier input, controlling the reference current to be between the programmed and unprogrammed memory cell currents.

Original Abstract Submitted

A semiconductor device includes a ROM, a differential sense amplifier and a multiplexer logic circuit. The ROM has memory cells in rows along word lines and columns along bit lines, and a reference column having reference transistors along a reference bit line. The multiplexer logic circuit couples a selected bit line to a first differential amplifier input and couples the reference bit line to the second differential amplifier input and controls a reference current of the reference bit line to be between a first bit line current of a programmed memory cell and a second bit line current of an unprogrammed memory cell.
