    摘要: A semiconductor memory includes storage cells (2) that have storage capacitors and transistors with an electrode, which is electrically biasable with two different electrical potentials (V1, V2) in order to open and close the transistor.

    摘要: A semiconductor memory and a method for operating the latter in order are provided, at least in testwise fashion, to deactivate a word line segment (12) of a segmented word line not via a first line (21) otherwise used for deactivation, but rather via a second line (22) via that the word line segment (12) is otherwise activated. The second line (22) can optionally be biased with a second potential (Vpp) provided for activation or with a third potential (Vgnd). If the third potential (Vgnd) is used for at least temporarily deactivating the word line segment (12), the word line segment can be driven via a switching element (17), which couples the word line segment to the second line (22), without the complementary switching element (16) of the driver segment (20) having to be used for deactivation. It can thereby be ascertained which of two switching elements (16, 17) of the driver segment is defective and whether or not the semiconductor memory will function in a manner free of errors after permanent replacement of the word line on account of a floating potential of the tested word line segment (12).

    摘要: An integrated memory can include a memory cell array, which has word lines for the selection of memory cells, bit lines for reading out or writing data signals of the memory cells, and a sense amplifier connected to bit lines of a bit line pair at one end of the bit line pair. In an activated state during a memory access, at least one activatable isolation circuit which is switched into one of the bit line pairs can isolate a part of the bit line pair, which is more remote from the sense amplifier from the sense amplifier. As a result, the effective capacitance of the bit lines can be significantly reduced during the memory access.
