    摘要: A method and structure for a photodiode array comprising a plurality of photodiode cores, light sensing sidewalls along an exterior of the cores, logic circuitry above the cores, trenches separating the cores, and a transparent material in the trenches is disclosed. With the invention, the sidewalls are perpendicular to the surface of the photodiode that receives incident light. The light sensing sidewalls comprise a junction region that causes electron transfer when struck with light. The sidewalls comprise four vertical sidewalls around each island core. The logic circuitry blocks light from the core so light is primarily only sensed by the sidewalls.

    摘要: An integrated redundancy eDRAM architecture system for an embedded DRAM macro system having a wide data bandwidth and wide internal bus width is disclosed which provides column and row redundancy for defective columns and rows of the eDRAM macro system. Internally generated column and row addresses of defective columns and rows of each micro-cell block are stored in a memory device, such as a fuse bank, during an eDRAM macro test mode in order for the information to be quickly retrieved during each cycle of eDRAM operation to provide an SRAM-like operation. A column steering circuit steers column redundant elements to replace defective column elements. Redundancy information is either supplied from a SRAM fuse data storage device or from a TAG memory device depending on whether a read or write operation, respectively, is being performed. The integrated redundancy eDRAM architecture system enables data to be sent and received to and from the eDRAM macro system without adding any extra delay to the data flow, thereby protecting data flow pattern integrity.

    摘要: A voltage control system and methodology for maintaining internally generated voltage levels in a semiconductor chip. The method comprises the steps of intermittently sampling an internal voltage supply level during a low power or “sleep” mode of operation; comparing the internal voltage supply level against a predetermined voltage reference level; and, activating a voltage supply generator for increasing the internal voltage supply level when the internal voltage supply level falls below the predetermined voltage reference level. The voltage supply generator is subsequently deactivated when the voltage supply level is restored to the predetermined voltage reference level. The sampling cycle may be appropriately tailored according to chip condition, chip temperature, and chip size. In one embodiment, the voltage control system and methodology is implemented in DRAM circuits during a refresh operation. The voltage levels that are suitable for sampling including DRAM band-gap reference voltage, boost wordline line voltage, wordline low voltage, bitline high voltage and bitline equalization voltages.
