Title: Testing machine of semiconductor storing circuit device
Inventor: URABE MAKOTO
IPC: G11C29/00
Filed: 1987-08-31
Abstract: PURPOSE:To restrict minimum the influence of the testing time to the whole of the testing operation, by arranging many pairs of address converting sections corresponding to many pairs of testing heads so as to drive the converting section and the corresponding testing head in one unit, so that one calculation is enough for testing. CONSTITUTION:Address converting sections 2 and 3 convert address informations from an address generating section 1 so as to correspond to the arrangement of physical elements to be tested in testing head sections 7 and 8, respectively. An address selecting section 4 selects converted address informations from one of the converting sections 2 and 3 which corresponds to the testing head 7 or 8 practicing the testing, and feeds the same to a format controlling section 5. The format controlling section 5 controls waveforms of the address information sent from the address selecting section 4 by a timing signal to alternatively supply the same to the head 7 or 8. Thus, one calculation immediately after reading the testing program is enough for testing the semiconductor storing circuit device, which results in restriction of influences by the testing time to the testing operation.
