Introduction

John W Hayn is a notable inventor based in Houston, TX, who has made significant contributions to the field of microcomputing. With a total of six patents to his name, he has developed innovative technologies that enhance the functionality and efficiency of electronic devices.

Latest Patents

Among his latest patents is the "Microcomputer with automatic refresh of on-chip dynamic RAM transparent." This invention describes a microcomputer device that integrates a ROM for program memory, a read/write memory, and a CPU within a single integrated circuit. The design includes input/output ports, interrupt, and operating mode controls that are memory mapped in the same logical address space as the program and read/write memory. The read/write memory consists of one-transistor type dynamic storage cells, where data bits are stored in capacitors. The refresh of this dynamic RAM occurs transparently to the CPU through an automatically-incremented address counter, utilizing a balanced, complementary array of two one-transistor cells for each data bit.

Another significant patent is the "Self-emulator microcomputer." This electronic digital processor system features an internal memory, an arithmetic and logic unit, registers, and peripheral control circuitry that supports internal, external, and emulator modes. In the internal mode, data and commands are stored in the internal memory, while in the external mode, commands are sourced from external memory. The emulator mode allows users to combine the microcomputer with external devices, enabling the emulation of a composite system with minimal hardware, thus facilitating software development for the composite system.
