A track and hold signal processing system is capable of driving 256 gray scale active matrix LCD displays at speeds limited only by the electrical characteristics of the display. The quiescent power dissipated by the system is substantially less than known track and hold drivers due to separation of the tracking circuit from the hold circuit resulting in optimization of the tracking function.

Dual mode track and hold drivers for active LCD'S

A technique of modifying a ROM mask to prevent external access of internal memory of an integrated circuit device. Patterns in the ROM mask are altered to permit implantation of components of a driver circuit such that these driver circuits are disabled. Disabling of the driver circuit prevents control signals from permitting external access of internal memory, therein allowing copy protection of the contents of the internal memory.
