    摘要: Dual field oxide isolation (34 & 42) is formed by oxidizing through a portion (44) of a silicon nitride layer (30), through an exposed portion (43) of a remaining portion (18) of a masking layer (16), and through an exposed portion (42) of a buffer layer (28), all of which overlie isolation regions (22) of the silicon substrate (12). The different portions vary the diffusion rate of oxygen so that different field oxide thicknesses are created in a single field oxidation cycle. Therefore, integrated circuits having both low voltage densely packed devices and high voltage devices can be fabricated on the same circuit.

    摘要: A device is disclosed having a low-voltage memory device. The device includes a first memory having a first memory topology and a second memory having a second memory topology, with both memories located in an integrated circuit. The first memory is a relatively high-density memory device, capable of storing large amounts of data relative to the second memory. The second memory is a low-voltage memory device capable of being accessed at low-voltages relative to the voltage at which the first memory can be accessed. Accordingly, the second memory is accessible when the integrated circuit is placed in a low-voltage mode of operation, which may represent a data retention state (sleep state) for the first memory or other portions of the integrated circuit. Thus, the device is able to store large amounts of data in the high density memory in a normal or active mode of operation, and also have access to the low-voltage memory during the low-voltage mode of operation.
