    摘要: A parity checking circuit is designed for continuous parity checking of content-addressable memory cells, and is configured such that during a parity check the number of parity checking steps per data word is the same as the number of bits in the original payload data word to be stored, with the parity checking circuit being formed from four transistors of the same conductance type. The parity checking circuit has a detector, which automatically detects the change in an information state of a memory cell. The detector is in the form of an automatic state device and has a number of catch latches.

    摘要: In order to test digital modules with functional elements, these are divided into test units (3) which respectively have inputs and outputs. Alternating test patterns are applied to the inputs of the test unit (3), and the test responses resulting from this are evaluated at the outputs of the test unit (3). The effect is then encountered that changes at each of the inputs of a test unit (3) do not all affect a particular output of this test unit (3). For every output of the test unit (3), it is possible to define a cone (5) whose apex is formed by the particular output of the test unit (3) and whose base comprises the inputs of the test unit (3) where, and only where, changes affect the particular output. According to the invention, the test pattern to be applied to the inputs of the test unit (3) is constructed of sub-patterns, whose length is in particular ≦ the number of inputs of the test unit (3) that are contained in the base of a cone (5). Owing to their shorter length, all possible combinations can be used for selecting the sub-patterns, so that a comprehensive function test of the test unit (3) can be carried out rapidly and with little outlay. In a digital module, this test function may in particular be implemented by a self-test unit (1) which can switch over the rest of the digital module into a test mode, generates the test patterns on the basis of sub-patterns, loads them into a test-pattern output register (2) for application to a test unit (3) and can evaluate the test response subsequently found at the outputs of the test unit (3) by means of an evaluation unit (16), or read it in for evaluation.

    摘要: A pulsed static flip-flop comprises a first logic device which combines a logic signal with a pulsed signal and outputs a set signal, a second logic device which logically combines the logic signal with a complementary pulsed signal and outputs a reset signal; and a latch device comprising storage means which hold a logic hold level to be tapped off as a stored logic state of the logic signal. The logic hold level is adjustable to a first logic level by a first push-pull transistor controlled by the set signal and to a second logic level by a second push-pull transistor controlled by the reset signal.
