MEMORY DEVICE AND ZQ CALIBRATION METHOD - A simplified explanation of the abstract
This abstract first appeared for US patent application 18448902 titled 'MEMORY DEVICE AND ZQ CALIBRATION METHOD
Simplified Explanation
The patent application describes a memory device that includes two calibration resistor interfaces connected to the same ZQ calibration resistor. It also includes a first master chip, first slave chips, a second master chip, and second slave chips, all commonly connected to the ZQ calibration resistor.
- The memory device operates in a command mode where it receives a ZQ calibration command through a first signal receiver and delays it using a second signal receiver.
- The first and second slave chips then start calibrating based on a ZQ flag signal.
- Once the calibration is completed, the first and second slave chips send a ZQ flag signal through second transmission terminals.
Potential Applications
- Memory devices in computer systems
- Embedded systems requiring memory calibration
Problems Solved
- Efficient calibration of memory devices
- Simplified calibration process
Benefits
- Improved performance and reliability of memory devices
- Simplified design and implementation of memory calibration
