    摘要: An integrated circuit comprises a plurality of memory cells and an array supply voltage control circuit. The plurality of memory cells are organized in rows and columns. A row comprises a word line and all of the memory cells coupled to the word line. A column comprises a bit line pair and all of the memory cells coupled to the bit line pair. The array supply voltage control circuit is coupled to the plurality of memory cells. The array supply voltage control circuit is for receiving a power supply voltage and for providing a reduced power supply voltage to memory cells of a selected column during a write operation in response to a voltage differential on the bit line pair of the selected column.

    摘要: A Read Only Memory (ROM) device includes a ROM array, a row address decoder, a column address decoder, a column multiplexer, and a control circuit. Data is stored in bit cells in the ROM array. The control circuit generates control signals for reading the ROM. The row address decoder selects a word line. The column address decoder enables a bit line. The data is sensed from a bit cell corresponding to the selected word line and the enabled bit line by a corresponding sense amplifier and delivered on a data output pin of the ROM. The control signals for enabling the bit line and the sense amplifier operate at a higher voltage than supply voltage of the ROM. This reduces the ROM read time.

    摘要: A method for form an integrated circuit device begins by growing a tunnel oxide (22). The tunnel oxide is exposed to a nitrogen containing ambient whereby nitrogen is incorporated at atomic locations at the interface between the tunnel oxide (22) and a substrate (11). This tunnel oxide and nitrogen exposure is performed for all of a floating gate active area (12), a high voltage active area (14) and a logic gate active area (16). A floating gate electrode (24) and interpoly dielectric regions (26 through 30) are then formed in the floating gate region (12). The tunnel oxide (22) is etched from the active areas (14 and 16) whereby nitrogen contamination (32) may remain. An optional sacrificial oxidation and a low temperature 830.degree. C. wet oxidation process utilizing HCL, H2 and O2 is then used to grow a high voltage gate dielectric (34) which has been shown to improve charge to breakdown characteristics by a factor of 1,000. After the formation of the high voltage gate oxide (34), a lower voltage logic gate oxide (36) is then formed.
