ABSTRACT:
A non-volatile, in-system programmable integrated-circuit switch has horizontal conductive lines and vertical conductive lines. A programmable interconnect cell including a floating gate transistor is provided at each intersection of a horizontal line and a vertical line. Each line is connected to a pin through a programmable I/O cell which includes a floating gate transistor. Each I/O cell can be programmed to configure the corresponding pin as an input pin or as an inverting or non-inverting output pin. The I/O cell can also be programmed to tri-state the pin or to fix the pin at a high or low voltage level. Each input pin can be connected to more than one output pins. A TTL-to-CMOS translator in each I/O cell is provided in the output section of the cell to reduce the translator output load and make the load, and hence the speed and power consumption of the switch, less dependent on the switch programming.
