Abstract:
1. A semi-conductor component test device with a shift register, several memory devices from which pseudo-random values representative of a minimum number of values of at least one of the group of a Bank address, a Row address, and a Column address to be used for testing a semi-conductor component are able to be tapped and emitted at corresponding outputs of the semi-conductor component test device, said minimum number of values of said at least one of said group being short of a required number of values, and whereby the shift register comprises a plurality of further memory devices, from which a like plurality of further pseudo-random values are able to be tapped and whereby a device is provided, from which the further pseudo-random values are emitted at at least one corresponding further output of the semi-conductor component test device to complete the required number of values for any, some or all of the Bank address, the Row address, and the Column address, wherein said minimum number of values is less than the required number of values.
