MEMORY MODULE AND MEMORY SYSTEM HAVING THE SAME - A simplified explanation of the abstract
This abstract first appeared for US patent application 17938780 titled 'MEMORY MODULE AND MEMORY SYSTEM HAVING THE SAME
Simplified Explanation
The abstract describes a memory module with a serial presence detector (SPD) that detects a module identification (ID) and generates a module ID or a register address corresponding to the module ID. A power management unit (PMU) responds to the module ID or register address and sets the on-time and off-time points of an internal clock signal. The PMU also generates internal power supply voltage based on the internal clock signal. The memory devices receive the internal power supply voltage and perform operations based on command/address signals.
- The memory module has a serial presence detector (SPD) that detects the module ID.
- The SPD generates either the module ID or a register address corresponding to the module ID.
- A power management unit (PMU) responds to the module ID or register address.
- The PMU sets the on-time and off-time points of an internal clock signal based on the module ID or register address.
- The PMU generates internal power supply voltage in response to the internal clock signal.
- The memory devices receive the internal power supply voltage and perform operations based on command/address signals.
Potential Applications
- Memory modules in computer systems
- Data storage devices
- Embedded systems
Problems Solved
- Efficient power management in memory modules
- Accurate detection and identification of memory modules
Benefits
- Improved power efficiency
- Enhanced performance and reliability of memory modules
- Simplified module identification and configuration
Original Abstract Submitted
A memory module includes a serial presence detector (SPD) configured to detect a module identification (ID) through at least one module position identification terminal, and generate at least one of the module ID and a register address corresponding to the module ID. A power management unit (PMU) is responsive to at least one of the module ID and the register address generated by the SPD. The PMU is configured to set an on-time point and/or an off-time point of an internal clock signal based on at least one of the module ID and the register address corresponding to the module ID, and further configured to generate at least one internal power supply voltage in response to the internal clock signal. A plurality of memory devices are also provided, which are configured to receive the at least one internal power supply voltage and perform an operation in response to command/address signals.
