The address control and switching circuitry selectively transmits read/write addresses and refresh addresses to the DRAM array, in order to perform refresh operations on the DRAM array without inhibiting read and write operations.

Abstract: In a system for severing conductive links by laser irradiation to repair electronic devices, multiple laser beams are deflected at high-speed to target selected links for processing by positioning laser spots in a two dimensional pattern during relative motion of a substrate and a beam delivery system. As link targeting flexibility is increased, selection may be required from a large number of addressable link pairs. Various embodiments advantageously use beam deflection and beam splitting to improve memory repair processing rates.

Abstract: A position encoder provides one or more trigger outputs based on position signals developed within the encoder, in addition to traditional position output signals used by other system components such as a motion controller. The trigger outputs may be used directly by a triggered device, bypassing the motion controller and obviating any separate trigger generation electronics. The trigger output(s) can be fully synchronous with the encoder's position output signal(s) with essentially no latency or jitter, increasing accuracy and providing improved system performance. The trigger functionality can be incorporated in a variety of encoder types (e.g., absolute and incremental) and technologies (optical, magnetic, inductive etc.), and used in conjunction with different position output signal formats (e.g., quadrature, serial).
