摘要:
Method and apparatus for storing records in non-uniform access memory. In various embodiments, the placement of records is localized in one or more regions of the memory. This can be accomplished utilizing different ordered lists of hash functions to preferentially map records to different regions of the memory to achieve one or more performance characteristics or to account for differences in the underlying memory technologies. For example, one ordered list of hash functions may localize the data for more rapid access. Another list of hash functions may localize the data that is expected to have a relatively short lifetime. Localizing such data may significantly improve the erasure performance and/or memory lifetime, e.g., by concentrating the obsolete data elements in one location. Thus, the two or more lists of ordered hash functions may improve one or more of access latency, memory lifetime, and/or operation rate.

A method of configuring a device having programmable logic is disclosed. The method comprises storing instructions in the device; selecting between one of the instructions stored in the device and an instruction coupled to an input/output port of the device; coupling the instruction to a non-volatile memory; and reading a configuration bitstream from the non-volatile memory based upon the selected instruction. A method of enabling a multi-boot configuration of a device having programmable logic is disclosed. The method comprises powering up the device using a first configuration bitstream from a first type of configuration device in response to a first command; receiving a reboot command; and reconfiguring the device using a second configuration bitstream from a second type of configuration device in response to a second command which is different than the first command. Circuits enabling a multi-boot configuration of a device having programmable logic are also disclosed.

An electro-optic device (100) has a first electrode (102), a second electrode (104), and an active polymer layer (106) disposed between the first and second electrodes. The active polymer layer is a blend of a high band gap material with a low band gap material. An electro-optic device has an anode, cathode spaced apart from the anode, and an active polymer layer (106) disposed between the cathode and anode. The cathode is constructed to provide both electron injection and hole blocking. A method of manufacturing an electrode-optic device include providing a substrate, forming a layer of Cs2CO3 (112) on the active polymer layer, and depositing a layer of metal (114) onto the layer of Cs2CO3 (112). The layer of Cs2CO3 (112) on the active polymer layer provides electron injection and hole blocking for the electro-opti device (100).

摘要:
A photodetector includes an anode that is transparent or partially transparent to light, a cathode and an active layer disposed between the anode and the cathode. The active layer includes a nanocomposite material that has a polymer blended with nanoparticles or organic electron trapping particles. The photodetector has a low dark current when not illuminated by light and has a high conductivity when illuminated by light, in which the light passes the anode and is absorbed by the active layer.

Multiple supply voltage select circuit for use with reduced supply voltage levels and method for using same are described. A first and second set of P-channel transistors are used for voltage pull-up at a common node using two supply voltages, respectively. A P-channel transistor from each of the sets is gated by output of a respective level shifter. Both of the level shifters are biased with a higher of the two supply voltages. First and second inputs are respectively provided to the level shifters and to gates of other P-channel transistors of each of the sets.
