摘要： A flash memory device employs a low current auto-verification programming scheme using multi-step programming voltage and cell current detection. The low current auto-verification programming scheme performs programming of memory cells by the application of programming voltages in step increments. For each programming pulse, the cell current of the memory cell is sensed to determine when the memory cell is programmed. The programming pulse is terminated when the cell current decreases below a reference current level.

摘要： A non-volatile memory device includes a sector pass/fail indicator circuit configured to store a pass/fail indicator for each sector in a first block of memory cells. The pass/fail indicator has a first value indicating the respective sector has failed erase verification and has a second value indicating the respective sector has passed erase verification. The sector pass/fail indicator circuit set the respective pass/fail indicators to the second value for one or more sectors in the first block after the respective sectors pass erase verification following a previous block erase operation of the first block. The first block is subjected to subsequent block erase operation where only word lines associated with the sectors having a pass/fail indicator having the first value are biased to the first bias voltage level.

摘要： A flash memory device uses a pair of parallely connected NMOS transistors with different voltage ratings to generate the reference current for the sense amplifier used in the read out operations. The reference current thus generated is temperature compensated with zero or near-zero temperature coefficient. In some embodiments, the pair of parallely connected NMOS transistors includes a high voltage NMOS transistor and a low voltage NMOS transistor or NMOS transistors with different gate oxide thicknesses.

摘要： A circuit for detecting a signal transition on an input signal includes a mirror delay circuit and an input blocking circuit to prevent signal glitches or undesired signal pulses from being passed to the output signal node, thereby preventing signal distortions from being detected as a valid signal transition. The input transition detection circuit generates stable and correct transition detection pulses having a consistent pulse width.

摘要： A search engine (100) having a controller (112), a memory (114), and a hash pointer unit (110). The memory (114) includes a database of search data and associate content, and the controller (112) uses individual search values to access the memory (114) to obtain individual search results. The controller (112) includes a hash function (116) that generates a hash value from a, typically large, search value into a, typically smaller, hash value that may be a hash collision. The controller (112) converts the hash value into a hash address which is communicated to the hash pointer unit (110), which receives the hash address and provides a hash pointer that is communicated to and used by the memory to look up respective search results. In this manner hash collisions are avoided and the size of the memory (114) is not a function of the degree of multi-way set-associativity used.
