    摘要: In a circuit configuration and a method for testing storage cells, all of the bit lines lead to one pair of fault lines which is first precharged with mutually-complementary logic levels. All of the storage cells of a word line are always read-out in parallel relative to one another. In the event of "no fault" the pair of fault lines retains its logic states, whereas in the case of a fault one of the fault lines changes its logic state through switching transistors. This is recognized and analyzed by a comparator circuit in the form of an XOR-circuit or an XNOR-circuit.

    摘要: A circuit gives each of the input signals at its inputs to a common circuit previously charged to a supply voltage through transfer transistors. When the logical condition is satisfied the common circuit remains charged; otherwise the charge changes. This is detected by a discriminator circuit and the result is indicated at the circuit output. The circuit may be of AND-, OR-, NAND- and NOR design.

    摘要: An integrated semiconductor memory of the DRAM type includes word lines and bit line pairs. Memory cells in a matrix are connected to the word lines and the bit lines. One evaluator circuit per bit line pair is connected to the bit lines. Each of the bit line pairs is divided into one bit line and one reference bit line during operation. A control line is provided. At least one coupling capacitor is provided for each of the bit lines and each of the reference bit lines having a first lead connected to the bit line pair and a second lead connected to the control line. A method for testing an integrated semiconductor memory of the DRAM type includes reading data stored in memory cells out of the memory cells, precharging bit line pairs to a precharge level before reading out, and feeding an additional potential to each bit line pair after precharging.

    摘要: An integrated semiconductor circuit includes word lines and bit lines. A memory region has at least one memory cell field with memory cells addressable through the word lines and the bit lines, and a number of evaluator circuits corresponding to the number of the bit lines. Each of the evaluator circuits is connected with one of the bit lines and divides the one bit line into two at least approximately identical bit line halves. Logic units of a block perform digital processing of data read-out of the memory region through the bit lines and evaluated. Each of the logic units is connected to the two bit line halves of one of the bit lines. Various operating modes of the block of logic units are selected with mode select signals.
