refresh signal造句

To avoid snow, some programs and games only copied data to the display on interrupt, as the Spectrum maskable interrupt was generated by the display vertical refresh signal.
A more sophisticated version displays a light color on the screen all the time ( grey, probably ) and measures the amount of time between the vertical refresh signal going to the TV and light entering the barrel of the gun.
With the rapid advent of 64 kbit + DRAM chips ( with an 8 bit RAS ), extra circuitry or logic had to be built around the refresh signal to synthesize the missing 8th bit and prevent blocks of memory being lost after a few milliseconds.
Another method, perhaps more universal but also more complex in terms of hardware, was to use an 8-bit counter chip, whose output would provide the refresh RAS address instead of the R register : the refresh signal from the CPU was used as the clock for this counter, resulting in the memory row to be refreshed being incremented with each refresh cycle.
