    • A non-volatile memory cell includes NMOS programming, read, erase, and control transistors having gate electrodes connected to a storage node. The erase and control transistors have interconnected source, drain, and bulk electrodes. The cell is programmed by setting source, drain, bulk, and gate electrodes of all transistors to a positive voltage. An inhibiting voltage is applied to source, drain, and bulk electrodes of the read transistor, while setting source and drain electrodes of the programming transistor to the positive voltage and the bulk electrode of the programming transistor to the positive voltage or the inhibiting voltage. Source, drain, and bulk electrodes of the control transistor are then ramped to a negative control voltage while ramping source, drain, and bulk electrodes of the erase transistor to a negative erase voltage and then back to the positive voltage. Source, drain. bulk, and gate electrodes of the programming, erase, and control transistors are then returned to the positive voltage, while setting the source, drain, and bulk electrodes of the read transistor to the inhibiting voltage.

    • A ROM array which provides for reduced size and power consumption. The bit cell of the ROM provides that a first type of information is stored in the bit cell when a transistor is disposed between a bit line and a word line, and a second type of information is stored in the cell when no transistor is disposed between the bit line and the word line. In the bit cell a contact between a bit line and a region where a transistor drain can be formed in a substrate is provided in those instances when a transistor is formed between the bit line and a word line. In those instances when a bit cell provides no transistors between the word line and the bit line, no contact is provided between the bit line and the region where a transistor drain can be formed. Further, where a bit cell does not provide a transistor between the bit line and the word line a bit cell region in the substrate can consist substantially of an isolating dielectric material.
    • 提供减小尺寸和功耗的ROM阵列。 ROM的位单元提供了当晶体管设置在位线和字线之间时,第一类型的信息被存储在位单元中,并且第二类型的信息被存储在单元中,当没有晶体管设置在单元之间时 位线和字线。 在晶体管形成在位线和字线之间的情况下,在位单元中提供位线和可以在衬底中形成晶体管漏极的区域之间的接触。 在位单元在字线和位线之间不提供晶体管的情况下,在位线和可以形成晶体管漏极的区域之间不提供接触。 此外,在位单元不在位线和字线之间提供晶体管的情况下,衬底中的位单元区域可以基本上由隔离电介质材料组成。
