ACTIVE RESISTOR ARRAY OF SEMICONDUCTOR MEMORY DEVICE: abstract simplified (17883842)
- This abstract for appeared for patent application number 17883842 Titled 'ACTIVE RESISTOR ARRAY OF SEMICONDUCTOR MEMORY DEVICE'
Simplified Explanation
The abstract describes an active resistor array in a semiconductor memory device. It includes multiple active resistors arranged in different regions, with isolation layers between them. The resistors are connected to selection transistors, which are controlled by the same gate layer. This design helps to improve the layout pattern and reduce process variation, resulting in better active resistance distribution.
Original Abstract Submitted
An active resistor array of a semiconductor memory device comprises a first active resistor in a first active resistor region; a second active resistor in the first active resistor region and arranged in parallel with the first active resistor, and an isolation element layer interposed therebetween; a third active resistor formed in a second active resistor region; a first selection transistor formed in a first selection transistor region and connected to the second active resistor; and a second selection transistor formed in a second selection transistor region and connected to the third active resistor. The first and second selection transistors are connected to the same gate layer. The gate layer of the first and second selection transistors is on the isolation element layer. Since example embodiments may help to ensure the uniformity of the layout pattern, active resistance distribution may be improved due to reduction in process variation.
