  • Patent number: 10825487
    Abstract: Apparatuses and methods for generating a voltage are described. An example apparatus includes first, second, and third bias circuits configured to provide first, second, and third bias signals, respectively. The example apparatus further includes a voltage output circuit configured to receive the first, second, and third bias signals. The voltage output circuit includes an output circuit and a current circuit. The output circuit includes an output node, a first node, and an input circuit configured to receive the first bias signal. The output circuit is configured to provide an output voltage at the output node having a magnitude based on the magnitude of the first bias signal. The current circuit includes a first transistor configured to receive the second bias signal and further includes a second transistor configured to receive the third bias signal. The first transistor and second transistor are coupled in parallel and to the first node.

  • Patent number: 5726994
    Abstract: A memory array is logically and/or physically divided into a plurality of blocks to allow test by individual blocks. When a plurality of column address strobe signals are provided and memory accessing is made by a plurality of bits to the memory array corresponding to the column address strobe signal, tests are independently conducted for each memory array by using the column address strobe signal.
