Title: Semiconductor storage device-based data restoration
Inventor: CHO BYUNGCHEOL
IPC: G11C7/10
Filed: 2012-07-19
Abstract: Embodiments of the invention provide a device and method for warm booting whereby data restoration occurs at the powering-on of the host, and can therefore be performed by the boot disk. Specifically, when the system is powered on, a backup controller will send a notification to a DMA controller indicating the data restoration is needed. The backup controller will automatically resorts contents of a backup storage device to main memory. During the process, when the host requests data, the DMA controller reads the data from the backup storage unit and sends it to the host. Then, once data restoration is complete, normal operations can commence.

Title: Flexible jelly roll type secondary battery
Inventor: CHUNG JOO-YOUNG
IPC: H01M50/105
Filed: 2013-11-07
Abstract: The present invention provides a jelly roll type electrode assembly, comprising: a negative electrode having a negative electrode active material coating layer formed by coating a negative electrode active material coated on both sides of a negative electrode current collector; a positive electrode having a positive electrode active material coating layer formed by coating a positive electrode active material coated on both sides of a positive electrode current collector; and a separation film interposed between the negative electrode and the positive electrode. The jelly roll type electrode assembly is formed by winding. The positive electrode and the negative electrode have non-coated portions on which the negative electrode active material and the positive electrode active material are not coated. The non-coated portions are formed such that the non-coated portions of the negative electrode and positive electrode, which are wound and stacked, are overlapped with each other so as to form a mirror image on the front surface and back surface of the jelly roll. The jelly roll type electrode assembly is capable of bending at the non-coated portion. The present invention also provides a pouch-type secondary battery comprising the electrode assembly, a battery pack, and a device. Using the flexible jelly roll type electrode assembly, a reversibly flexible jelly roll type secondary battery, which may avoid the problem of the delamination of the electrode active material from the surface of the current collector, can be obtained.
