Filed: 2002-07-25
Abstract: <P>PROBLEM TO BE SOLVED: To provide a sense amplifier which has a small detection error of a readout signal and small power consumption, a bit line circuit, a storage device, and a method of amplifying the readout signal.  <P>SOLUTION: When a control signal ENN reaches a high level under the condition that bit lines (BL, BLZ) and the input terminals (SA, SAZ) of an amplifier circuit are connected by a CMOS switch circuit, the amplifier circuit starts amplifying the readout signal, and the amplified signal is stored. After amplification of the readout signal is started and the time of delay by a delay circuit U1 elapses, a control signal GEN1 and a control signal GEN2 outputted by the delay circuit U1 change and the connection between the bit lines and the amplifier circuit is released. Thus, since the bit lines and the amplifier circuit are disconnected from each other after the amplifying operation has proceeded to some degree while a small potential difference at the time of starting the amplification is maintained by a current from the bit lines, it is possible to make detection errors of the readout signal harder to occur.  <P>COPYRIGHT: (C)2004,JPO
