Memory device and method of operation thereof

An operation method of a memory device, comprising:

• disconnecting, in a read operation, a first input and output line pair and a second input and output line pair;
• pre-charging, in the read operation, the second input and output line pair at a pre-charge voltage;
• amplifying, in the read operation, a voltage of the first input and output line pair;
• and
• connecting, in the read operation, in order for the amplified voltage of the first input and output line pair to be delivered to the pre-charged second input and output line pair, the first input and output line pair and the second input and output line pair.

A memory device comprising:

• a first input and output line pair;
• a sense amplification circuit configured to amplify a voltage of the first input and output line pair to output the same to the first input and output line pair;
• a second input and output line pair;
• a pre-charge circuit configured to pre-charge the second input and output line pair at a pre-charge voltage;
• and
• a first switch circuit connecting or disconnecting the first input and output line pair and the second input and output line pair according to a first control signal.
