STORAGE DEVICE AND A POWER MANAGEMENT DEVICE - A simplified explanation of the abstract
This abstract first appeared for US patent application 17898588 titled 'STORAGE DEVICE AND A POWER MANAGEMENT DEVICE
Simplified Explanation
The abstract describes a storage device that includes a controller, memory devices, and a power management device. The controller is connected to an external host and the memory devices store data. The power management device outputs an internal power voltage for the memory devices using an external power voltage received through the interface. It also has a flag signal pad to receive a flag signal from the controller when the controller fails to recognize at least one of the memory devices. When the flag signal is received, the power management device changes the slope of the internal power voltage and supplies it to the memory devices.
- The storage device includes a controller, memory devices, and a power management device.
- The controller is connected to an external host through an interface.
- The memory devices are used to store data.
- The power management device outputs an internal power voltage for the memory devices.
- The internal power voltage is generated using an external power voltage received through the interface.
- The power management device has a flag signal pad to receive a flag signal from the controller.
- The flag signal is sent when the controller fails to recognize at least one of the memory devices.
- When the flag signal is received, the power management device changes the slope of the internal power voltage.
- The power management device then supplies the internal power voltage with the changed slope to the memory devices.
Potential Applications
- Data storage devices such as hard drives, solid-state drives, or flash drives.
- Embedded storage systems in various electronic devices like smartphones, tablets, or laptops.
- Cloud storage servers and data centers.
Problems Solved
- Failure of the controller to recognize memory devices can lead to data loss or system instability.
- Inefficient power management can result in excessive power consumption and reduced device lifespan.
- Inadequate power supply can cause memory devices to malfunction or fail.
Benefits
- Improved reliability and stability of storage devices.
- Efficient power management for optimized performance and energy savings.
- Enhanced data integrity and reduced risk of data loss.
- Extended lifespan of storage devices.
Original Abstract Submitted
A storage device including: a controller configured to be connected to an external host through an interface; a plurality of memory devices configured to store data; and a power management device configured to output an internal power voltage for an operation of the plurality of memory devices using an external power voltage received through the interface and having a flag signal pad for receiving a flag signal from the controller when the controller fails to recognize at least one of the plurality of memory devices, wherein, when the flag signal is received, the power management device changes a slope of the internal power voltage, and supplies the internal power voltage having the changed slope to the plurality of memory devices.
