    摘要: A system for programming arrays of floating gate memory cells reduces programming current requirements, and reduces wordline and bitline stress during programming. A word-to-be-programmed into a floating gate memory array is divided into a plurality of smaller subwords. Only one subword is programmed at a time, thereby reducing programming current requirements. Additionally, subwords which are successfully programmed are not reprogrammed even if bits in other subwords do not program properly. This creates less wordline stress than previous systems which program an entire word at once, thereby requiring subwords which program successfully to be reprogrammed along with subwords which fail to program. Finally, within each subword only those bits which failed to program are reprogrammed, thereby reducing bitline stress during reprogramming for those bits which were successfully programmed.

    摘要: A voltage regulator includes an amplifier, a power device, a delay signal generator, and a voltage-generating circuit. The amplifier generates a control signal according to a reference voltage and a feedback voltage. The power switch generates the output voltage by regulating the output current according to the switch control signal. The delay signal generator generates a plurality of sequential delay signals each having distinct delay time with respect to an externally applied power-on burst signal. The voltage-generating circuit provides an equivalent resistance for generating the feedback voltage corresponding to the output voltage, and regulates the output voltage by adjusting the equivalent resistance according to the plurality of sequential delay signals.

    摘要: In a floating gate memory that has a buffer that can be coupled to a set of floating gate memory cells in the memory, a method of writing to a selected portion of the set of floating gate cells. For example, a method of writing a byte to a floating gate memory where the memory uses a page buffer reads and writes to an entire row of cells at a time. Store contents of the set of floating gate cells into the buffer, store the data into a portion of the buffer corresponding to the selected portion of the set of floating gate cells, and store contents of the buffer into the set of floating gate cells. An improved floating gate memory is disclosed in which data may be loaded into a portion of the floating gate cells in a set of cells that may be coupled to a buffer.
