Abstract
An improved computer system is implemented with an integrated circuit computer having integrated circuit (IC) memories and using a keyboard input and sound output to communicate with an operator. Provision is made for a dynamic memory with a memory refresh arrangement. Memory refresh is synchronized with computer control signals to minimize contention or conflicts with computer operations and to share control circuitry. Improved control system architecture, computer architecture, and memory architecture are provided that are particularly suitable for operator interaction, integrated circuit data processors, and dynamic memories.
