A system and method are disclosed for generating a transition in a laser control signal at a precise point in time. A write strategy processor is configured to input a sequence of data and to determine a transition in a laser control signal from the sequence of data. The transition is specified by a number of pulse clock units and a delay. A write pulse generator is configured to input the number of pulse clock units and the delay and to generate a transition by creating a signal having a transition at the time specified by the number of pulse clock units and delaying the transition by the specified delay.

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.
