摘要
Provided is a bitline isolation circuit in a sense amplifier generating an isolation signal for controlling an isolation circuit to isolate a connection between a bitline sense amplifier and a bitline at the beginning of sensing of a read operation, according to an output of a control unit generating an isolation control signal, a start signal of the bitline sense amplifier, and a memory block select signal. The control unit includes: a write pulse generation unit for generating a first control signal, according to a first input signal as a bank address signal latched for every clock, a second input signal generated when a write or a read command is inputted, and a third input signal having a different level according to the read or the write command; and an isolation control signal generation unit for generating the isolation control signal, according to the first control signal and the second control signal having a different level according to a row active operation and a precharge operation.
