  • Publication number: 20070281222
    Abstract: An opaque defect is processed by scanning with a high load or height fixed mode using a probe harder than a pattern material of a photomask at the time of going scanning, and is observed by scanning with a low load or intermittent contact mode at the time of returning scanning so as to detect an ending point of the opaque defect by the height information. When there is a portion reaching to a glass substrate as an ending point, this portion is not scanned by the high load or height fixed mode in the next processing, and only a portion not reaching to the ending point is scanned by the high load or height fixed mode.

  • Patent number: 5956520
    Abstract: An external bus I/F section has a function in which, when a bus access is requested by an instruction execution section, high-order several bits of a logical address generated by a CPU are outputted from an output terminal to the outside of a chip, as a space identifier for indicating which of an integrated ROM space, an integrated RAM space, and the external space is accessed by a currently executed program. A part of an address generated by the CPU is used so that the space which is accessed by the currently executed program is known from the outside in real time without requiring an external hardware.

  • Patent number: 5870594
    Abstract: The timing of digital signal sampling at a receiver is continuously adjusted relative to a master clock used to initiate sending, by controlling a phase difference between the receiver sampling clock and the master clock in accordance with feedback of an error signal determined by detecting deviation of sampling clock timing from desired reference timing during both start-up operation and normal operation. Propagation delay scattering in the individual devices is compensated for by setting the sampling clock at a desired reference timing at start-up. Propagation delay scattering caused by fluctuation during device operation is compensated for by detecting the deviation of the sampling clock timing from reference timing based on received digital signals during normal operation and then continuously correcting the sampling clock timing on the basis of the detection result.

  • Patent number: 5794020
    Abstract: A first variable delay circuit delays the reception data from the transmitting unit which is outputted from an input buffer and generates the delayed data to a data unidentifying time detecting portion. First and second latches have latch timings at regular intervals before and after a latch timing of a third latch for receiving and outputting by second and third variable delay circuits, respectively. In an adjusting operation, delay amounts of the second and third variable delay circuits are fixed to a value which is sufficiently smaller than a transfer period, a delay amount of the variable delay circuit is increased, a judging circuit detects a preceding edge of the reception data, subsequently, the delay amounts of the second and third variable delay circuits are sequentially increased while maintaining to the same value, and a following edge of the reception data is detected. In this instance, the timing of the third latch is set to the optimum point of the maximum margin.

  • Patent number: 5544340
    Abstract: A method of controlling a cache memory disposed between a CPU and a main memory, wherein pairs of data and an address to be written in the cache memory are stored into a buffer memory. A plurality of pairs of data and an address read from the buffer memory are processed to compare the address fields thereof. Based on results of the comparisons, there is determined a write control for writing the data in the cache memory which has been subdivided into a plurality of banks. As a result, the plural pairs of data and an address are written into the plural banks of the cache memory, the addresses of the respective pairs being different from each other. With the provisions set forth above, the write operation can be independently conducted for each bank of the cache memory, thereby improving the write throughput.

  • Patent number: 5394533
    Abstract: A data cache, for use in a memory having an address space including tag addresses for identifying blocks of storage locations and a set of select addresses for identifying storage locations in a block, includes a set select decoder that decodes only a subset of said set of select addresses that identify sub-blocks of storage locations located at the upper and lower boundaries of a block. Thus, data in storage locations accessed by addresses near block boundaries which have a high number of bit transitions is registered to the cache so that the high number of bit transitions does not have to be driven on an external bus so that noise is reduced.
