  • Synchronous integrated memory
    Patent number: 6275445
    Abstract: A memory has data lines through which data connections are connected to groups of memory cells via a synchronizing unit. The synchronizing unit is disposed adjacent to the cell group and has a clock input to which an internal clock signal is fed. In the event of a write access to the memory, the synchronizing unit synchronizes with the internal clock signal data signals that are fed via the data connections and are synchronous with an external clock signal.

  • Integrated memory
    Patent number: 6272035
    Abstract: A memory has an input circuit, which is provided adjacent to two groups of memory cells and via which two global data lines are connected to two local data lines. The memory has two operating states during which it feeds the data provided on the global data lines in respective different assignments to the two local data lines.

  • Integrated memory having memory cells disposed at crossover points of word lines and bit lines
    Patent number: 6256219
    Abstract: An integrated memory has first control lines, which run in the direction of bit lines, and a second control line, which runs in the direction of word lines. First control inputs of in each case at least two switching elements that are connected to different sense amplifiers are connected to the same first control line. The second control inputs of the switching elements are connected to the second control line. The invention makes it possible to reduce the number of first control lines running in the direction of the bit lines.
