Abstract: An integrated circuit serial access type memory, notably in EEPROM technology, includes a data input (DI) and a data output (DO), a defined memory plane (MM) organized in memory words, as well as a set (LAT) of column registers, one such register being associated with at least one memory word of the memory. The memory includes a writing circuit and/or a reading circuit. The writing circuit operates, during an operation for writing a binary word in a given memory word (M0-M7), for loading the binary data of the binary word received in series at the data input (DI) directly into respective storage and switching latches (HV0-HV7) of the column register (R1) associated with the memory word (M0-M7). The reading circuit operates, during an operation for reading a binary word in a memory word, for reading successively the binary data stored in the memory cells of the memory word and for delivering directly, in serial form, each binary data read to the data output (DO) of the memory.

Abstract: At a charging phase, a capacitor (PC) is charged through two complementary charging transistors (TR1, TR2) connected in series to a first terminal (T1) of the capacitor (PC). At a voltage multiplication phase, an input voltage (Vdd) is delivered to the second terminal (T2) of the capacitor and an output voltage (Vout), increased with respect to the input voltage, is recovered at the first terminal (T1) of the, capacitor, and the capacitor is discharged during a discharging phase. During three phases, the substrate (BK2) of the charging transistor (TR2) directly connected to the first terminal (T1) of the capacitor is slaved to the source (S2) of this same charging transistor (TR2), while still keeping the source-substrate junction and the drain-substrate junction of this charging transistor (TR2) reverse-biased.

Abstract: A column register of an integrated circuit memory, notably in EEPROM technology, is utilized in a method of writing a data word of 2p bits in the memory, where p is a non-zero whole number. The method includes the following steps: 1) erasing all the cells of the word; 2) loading 2q data in 2q high-voltage latches (HV1, HV3, HV5, HV7), and loading 2p−2q other data in the 2p−2q low-voltage latches (LV0, LV2, LV4, LV6); and 3) programming 2q cells of the memory (M0, M2, M4, M6) as a function of the data memorized in the 2q high-voltage latches; as well as repeating 2p−q−1 times the following steps: 4) loading, in the 2q high-voltage latches, of 2q other data that were loaded in the 2q low-voltage latches at step 2); and 5) programming 2q other cells of the memory (M1, M3, M5, M7) as a function of the data memorized in the 2q high-voltage latches.

Abstract: A method for scaling a binary image by a non-integer factor with quality enhancement. The method includes the steps of: selecting a pel in an input bitmap which represents the image; selecting a neighborhood centered about the selected pel; comparing the selected neighborhood with a set of preselected image feature patterns representing typical image features; and when the selected neighborhood matches an image feature pattern, writing a block of bits to the output bitmap. The block of bits to be written is obtained by subsampling an image enhancing tile that corresponds to the matched image feature pattern. The size and shape of the block and its destination within the output bitmap are determined by the location of the selected pel within the input bitmap. The process is repeated for each pel within the input bitmap resulting in an output image bitmap which represents a non-integer scaled version of the input bitmap with image quality enhancement.
