Abstract
A new RSFQ latch, the DC-Resettable Latch (DCRL), is introduced. The DCRL functions like a standard nondestructive readout register (NDRO), except that it requires a dc current or current pulse to reset. This allows the DCRL to be used as a memory element in large memory blocks, where the entire block can be erased with a current pulse from a single threaded current line instead of unwieldy pulse distribution circuitry. The reset current can be applied by off-chip control logic, or on-chip bipolar current elements such as HUFFLEs. However, the DCRL is most useful as the base building block of complex reprogrammable RSFQ circuitry. © 2005 IEEE.
