Solution Overview
Problem
Conventional data transmission circuits in nonvolatile memory systems face challenges in operating at high speeds due to significant loading on output lines, which slows down the transfer of data from input to output lines.
Innovation Solution
A data transmission circuit comprising an input line selection unit, a data sensing unit, and a data amplification unit that senses data on selected input lines and amplifies the output line based on the sensing result, allowing for faster data transfer by precharging the output line before connecting the input line and driving it to a predetermined voltage based on the sensed data.

1Speed
If data is transferred directly from input line to output line without precharging, then the circuit operation is simpler, but the data transfer speed is slow due to significant loading on the output line
Solution Approach 1:
The output line is precharged to a predetermined voltage level before data transfer begins. This preliminary action prepares the output line to quickly accept and propagate the data signal from the input line, thereby increasing data transfer speed without significantly complicating the overall circuit operation
Solution Approach 2:
The data transfer process is divided into distinct phases: precharging phase where the output line is prepared, and data transfer phase where actual data propagation occurs. This segmentation allows each phase to be optimized independently, improving overall transfer speed while maintaining manageable circuit complexity
2Speed
If the output line is precharged and driven to predetermined voltage, then data transfer speed improves, but the time required for voltage stabilization increases
Solution Approach 1:
The output line is precharged to the target voltage level before data arrival, so that when data is transferred, the line is already in the correct voltage state. This eliminates the need for slow voltage buildup during data transfer, reducing overall stabilization time while maintaining high transfer speed
Solution Approach 2:
By precharging the output line in advance, the circuit skips the slow voltage establishment phase during actual data transfer. The data signal can immediately propagate through the pre-prepared output line, rushing through the transfer process without waiting for voltage stabilization
