A memory accessing method is described which is particularly useful with the Multibus where a dynamic memory is employed. When the memory is accessed without a refresh collision, a ready signal is generated before the acknowledgement signal. This saves considerable time since the time between the placement of the data on the bus and the CPU's sensing of the data is reduced.

Memory accessing method

A buffer utilizing MOS devices for coupling a computer input data line and a computer output data line to a single input/output port is disclosed. The buffer receives a control signal generated by computer port control means at the beginning of any buffer cycle when data is to be accepted by the buffer.

Programmable single chip MOS computer

An MOS digital computer incorporated on a single chip (monolithic structure) which includes a central processing unit (CPU), random-access memory (RAM), and a programmable read-only memory (PROM). A program counter is used to fetch instructions stored in the erasable PROM, and may also be used to fetch instructions from an external memory. The PROM may also be externally addressed for testing, or may be electrically isolated from the remainder of the computer to permit execution of external instructions for testing the CPU and RAM.
