Abstract
Abstract A programmable speed/logic arrangement for integrated devices having logic matrices which permits a user to determine the method by which the a logic matrix of an integrated circuit is switched between a low power standby and a high power operation mode. The arrangement includes a switching circuit for switching the logic matrix between modes, switch operating circuit responsive to at least one of internal and external wake-up pulses for operating the switching circuit, and an internal pulse generator for selectively generating a wake-up pulse internally of the matrix. The logic matrix is provided with a specific addressable location which is responsive to an appropriate address to generate the internal wake-up pulse as well as a dedicated input responsive to an externally generated wake-up pulse. Further, high/low power fuses or E/EE CMOS devices can be employed to programmably connect the logic matrix to different levels of high power sources. The plural power sources may be a plurality of parallel switches for each column.
