摘要:
A computer program, method, and apparatus for narrowing data down to detect duplicate data in a short time. A computer functions as a syntax tree constructor for creating a syntax tree by extracting a plurality of letters existing at prescribed discrete positions from the character string of each of the data and a duplicate data detector for detecting some data as possible duplicate data if the data have reached a same leaf node of the syntax tree.

The solid state imaging device comprises a solid state imaging element for storing light generating charges in a high concentration buried layer under a channel, modulating a threshold voltage, and detecting a light signal, a signal output circuit 105 for outputting a difference voltage between a first source potential after light modulation and a second source potential before the light modulation, wherein the signal output circuit 105 stores the first source potential and the second source potential in a first line memory (Lms) and a second line memory (Lmn) each formed of an input capacitor which is connected to a source region of a light signal detecting insulated gate field effect transistor respectively and outputs a difference voltage (Vout=VoutS−VoutN) between the first source potential and the second source potential via switched capacitor circuits.
摘要:
A semiconductor integrated circuit having a memory and an adjacent peripheral circuit generating minority carriers which can destroy data in a portion of the memory at low temperatures. The load resistance in the portion is made lower or the storage capacity is made higher in the portion than in the remainder of the memory so that at low temperatures data is not lost and the energy consumption of the circuit is not unduly increased.
