Abstract: A memory test circuit is provided. The memory test circuit is disposed in a memory chip and electrically coupled to a memory macro of the memory chip. A high speed clock receives an input signal and an external clock signal. The input signal includes a plurality of test bits. A finite state machine controller provides a pattern type. A pattern generator generates and provides a test signal to at least one memory cell of the memory chip to write the test signal to the at least one memory cell based on the pattern type and the external clock signal. A test frequency of the test signal is determined based on the high speed clock. An output comparator outputs a comparison signal based on a difference between the test signal and a readout signal corresponding to the test signal read from the at least one memory cell.

Abstract: A memory test circuit is provided. The memory test circuit is disposed in a memory array and including: a test array, including test cells out of memory cells of the memory array; a write multiplexer, configured to selectively output one of a test signal and a reference voltage based on a write measurement signal, wherein the test signal is output to write into at least one test cell and the reference voltage is output to a sense amplifier; and a read multiplexer, configured to selectively receive and output one of a readout signal corresponding to the test signal and an amplified signal based on a read measurement signal, wherein the readout signal is read from the at least one test cell and the amplified signal is obtained for a read margin evaluation from the sense amplifier by amplifying a voltage difference between the readout signal and the reference voltage.

Abstract: A circuit includes a sense amplifier, a first clamping circuit, a second clamping circuit, and a feedback circuit. The first clamping circuit includes first clamping branches coupled in parallel between the sense amplifier and a memory array. The second clamping circuit includes second clamping branches coupled in parallel between the sense amplifier and a reference array. The feedback circuit is configured to selectively enable or disable one or more of the first clamping branches or one or more of the second clamping branches in response to an output data outputted by the sense amplifier.

Abstract: A displaying method for an electronic device is provided. The electronic device comprises a storage device storing at least a photo group and a sharpness look-up table. The photo group includes a plurality of photos of an object successively captured in different focuses and the sharpness look-up table records sharpness information of each of the photos. The displaying method comprises displaying a cover photo of the photo group and receiving a selecting signal indicating a position on the cover photo. According to the position, the sharpness information of each photo in the sharpness look-up table is checked to determine a photo to be displayed, wherein the sharpness information of the determined photo shows a sharpness score at the position of the determined photo is the maximum among the sharpness scores at the positions of the photos in the photo group. The determined photo of the object is displayed.

Abstract: Detection and prevention of botnet behavior is accomplished by monitoring access request in a network. Each request includes a domain of content to access and a path of content to access, and each path includes a file name and query string. Once obtained, the query strings for each of these requests are normalized. A signature is then created for each of the normalized query strings. The obtained requests can then be grouped by signature. Once the requests have been grouped by signature, each grouping is examined to identify suspicious signatures based on common botnet behavior. Suspicious requests are used in back-end and front-end defenses against botnets.

Abstract: A peer to peer network, a method, a computer program product for a new node joining the network and a computer readable medium are disclosed. The peer to peer network comprises a plurality of nodes and a new node. Each of the nodes has its own partner list. Each of the partner lists records nodes that are able to provide data to the owner of the partner list. The nodes recorded in the partner list are called the partners of the owner of the partner list. When the new node intends to join the network, each of the nodes of the network decides whether to accept the new node according to the number of its partners but not according to a random manner. The stability of the network can be enhanced and the load of the network can be balanced.

Abstract: A multimedia broadcast system and method supporting peer-to-peer (P2P) coordinated code conversion are provided. The method includes forming, by a data source device, one or more data segments from multimedia data, and then scattering the data segments to a P2P network formed by the viewers; wherein an individual P2P device is connected with one or more P2P devices via a network system to form a partner group, and then acquires code conversion degrees of each data segment to serve as a basis for strategically adjusting the coordinated code conversion of said multimedia data. The coordinated code conversion mechanism is supported by common P2P multimedia broadcast systems, and is capable of rapidly converting the multimedia data in one format into multimedia data in other different media formats, thereby enabling real-time broadcasting of data in different formats to clients using P2P networks of various specifications.
