Abstract: PURPOSE:To perform a file recovery job at a high speed to a defective area by providing an instruction to carry out unconditionally read/write actions in case a defective sector is detected in a read/write mode of an input/output device of a file system. CONSTITUTION:Control information and time information corresponding to an F read instruction are set to a sequence circuit 33 by a processor 22 when the F read instruction is executed. Then the circuit 33 is started. The control information is previously set from the processor 22 so that a CRC check signal is not delivered from the circuit 33. Thus the read data is sent to a processor from a data buffer 25 via a DMA bus with no detection of both address and data marks. Then the read data is retrieved by the processor together with those address and data marks. Thus the address and data parts starting at said address and data marks respectively are discriminated for check of the propriety of both parts.

Title: Probe device
Inventor: DANIERU JIEI AIRESU
IPC: H01L21/66
Filed: 1988-05-19
Abstract: PURPOSE:To shorten the testing time by a method wherein a probe is caused to move up and down in response to a controlling signal so that the contact of a probe tip with test points on an IC may be properly controlled. CONSTITUTION:This is a probing unit capable of selectively getting into contact with test points on an IC 12 prior to packaging and includes a probe 16 equipped with a conducting wire probe tip 28 that establishes connection between a test point and a testing unit. A position controlling unit 18 responding to controlling signals from outside moves the probe 16 up and down, which causes the probe tip 28 to be in contact with or away from a test point. Accordingly, only a probe needed for a specified IC test may be selected to be brought into contact with IC test point. It follows therefore that in a series of measurements on various test points on an IC, a probe is prevented from its unnecessary contact with points other than that to be tested. This shortens the testing time.
