    摘要: A method for testing semiconductor chips is disclosed. In one embodiment, a chip to be tested which has a test logic, at least one test mode is set, the test modes are executed in the chip and test results or the status of the test modes are output from the chip. The method includes providing a chip having at least one first register set having a plurality of registers and at least one second register set having a plurality of registers, at least one register of the first register set and at least one register of the second register set being 1:1 logically combined with one another. A first serial bit string is stored, the bit sequence of which can be assigned to at least one test mode, in the first register set. A bit sequence is transmitted for application of the logical combination between the first register set and the second register set to the first bit string stored in the first register set. The test results are read out by means of a serial second bit string.

    摘要: A method for on-chip testing of memory cells of a cell array of an integrated memory circuit includes writing different data patterns to memory cells and reading the different data patterns from the memory cells in order to test the memory cells. A basic data pattern is stored in a data word register and read out by applying a data control signal provided by a controller. In addition to the basic data pattern, at least one further data pattern, which differs from the basic data pattern and is stored in a data word register section, is accessed in a targeted manner through the use of the data control signal. As a result the test proceeds rapidly and yields extensive test information.

    摘要: An integrated semiconductor memory device includes a first memory zone, a second memory zone, first address connections and a second address connection. A second address signal present at the second address connection specifies the access to the first or second memory zone, whereas it is specified via first address signals at the first address connections which memory cell is accessed within the first or second memory zone. In a first memory configuration, all address connections are driven externally with address signals and the access to a memory cell in the first or second memory zone is controlled. In a second memory configuration, only the first address connections are driven externally whereas a signaling bit in a mode register regulates the access to the first or second memory zone. This provides for access to the second memory zone even if there is no possibility of externally driving the second address connection.
