    摘要: Thermal cooling structures of diamond or diamond-like materials are provided for conducting heat away from semiconductor devices. A first silicon-on-insulator embodiment comprises a plurality of thermal paths, formed after shallow trench and device fabrication steps are completed, which extend through the buried oxide and provide heat dissipation through to the underlying bulk silicon substrate. The thermal conduction path material is preferably diamond which has high thermal conductivity with low electrical conductivity. A second diamond trench cooling structure, formed after device fabrication has been completed, comprises diamond shallow trenches disposed between the devices and extending through the buried oxide layer. An alternative diamond thermal cooling structure includes a diamond insulation layer deposited over the semiconductor devices in either an SOI or bulk silicon structure. Yet another embodiment comprises diamond sidewalls formed along the device walls in thermal contact with the device junctions to provide heat dissipation through the device junctions to underlying cooling structures. It is also proposed that the foregoing structures, and combinations of the foregoing structures, could be used in conjunction with other known cooling schemes.

    摘要: A method and apparatus for refreshing data in a dynamic random access memory (DRAM) cache memory in a computer system are provided to perform a data refresh operation without refresh penalty (e.g., delay in a processor). A data refresh operation is performed with respect to a DRAM cache memory by detecting a request address from a processor, stopping a normal refresh operation when the request address is detected, comparing the request address with TAG addresses stored in a TAG memory, generating refresh addresses to refresh data stored in the cache memory, each of which is generated based on an age of data corresponding to the refresh address, and performing a read/write operation on a wordline accessed by the request addresses and refreshing data on wordlines accessed by the refresh addresses, wherein the read/write operation and the refreshing of data are performed simultaneously.

    摘要: The speed of memories is increased by trading memory density (or area) for speed (or cycle time). An n by n memory array is used to reduce the memory cycle time by 1/n. For example, if an existing memory cycle time is 6 ns, in order to achieve a 3ns (or n=2) cycle time, a 2 by 2 memory array is used. Or, in order to achieve a 1ns cycle time (or n=6), then a 6 by 6 memory array is used.

    摘要: A semiconductor memory device accessed with wordlines and bitlines has memory cells which operate at high performance with lower power consumption and have a high density. Each of the memory cells has pass transistors connected to a corresponding wordline and a corresponding pair of bitlines, and the pass transistors are gated by a signal of the corresponding wordline. The semiconductor memory device includes a wordline drive unit for selectively driving the wordlines in response to a row address. A wordline driver in the wordline drive unit boosts a corresponding wordline in a positive direction when the corresponding wordline is activated to access the memory cell and boosts the corresponding wordline in a negative direction when the corresponding wordline is inactive. By boosting the wordline in the positive direction, the performance of the memory cells is enhanced, and by boosting the wordline in the negative direction, a leakage current in the pass transistors with a low-threshold voltage is prevented.
