Abstract: A semiconductor memory includes a control circuit for generating an internal read command signal depending on an externally applied read command signal. A clock generating circuit generates a system clock signal and a time shifted clock signal generated by a DLL circuit. A latency counter circuit comprises a first control circuit for generating a first control signal and a second control circuit for generating a second control signal. The first control signal is used to latch the internal read command signal in one of FIFO-latching cells. The latching is carried out in a system clock domain. The second control signal is used to release a time shifted internal read command signal from one of the FIFO-latching cells in a DLL clock domain. The relationship between first and second control signals determines a CAS latency by which data items appear at a data terminal synchronous with an externally applied clock signal.

Abstract: In a semiconductor memory, there is capacitive coupling between bit lines that largely run in parallel. Outer sections of the bit lines are connected via respective switches to a sense amplifier arranged between the switches. When a memory cell is being read, the capacitive interference by other bit lines that are not coupled to the memory cell being read is kept as low as possible before the start of amplification by the sense amplifier by turning on the switches in that bit line. During the amplification phase, the remote outer section of that bit line is disconnected using the appropriate switch. In one embodiment, the capacitance of the bit line that is not connected to the memory cell to be read is increased further by additionally activating a precharging circuit.
