Abstract: An electrode assembly and a lithium ion electric roll having the same are provided. The electrode assembly includes: a first electrode unit; a first anti-puncture cushion; in which the first electrode unit includes a first electrode sheet, an second electrode sheet, and a separator, the second electrode sheet comprises a second top edge and a second bottom edge along the length direction of the first electrode unit; an edge of the first anti-puncture cushion exceeds the second electrode sheet from the second top edge or the second bottom edge along the length direction of the first electrode unit.

Abstract: A system and a method for writing cache data and a system and a method for reading cache data are disclosed. The system for writing the cache data includes: an on-chip memory device, configured to cache received write requests and write data associated with the write requests and sort the write requests; a request judging device, configured to extract the sorted write requests and the write data associated with the write requests according to write time sequence restriction information of an off-chip memory device; and an off-chip memory device controller, configured to write the write data extracted by the request judging device in the off-chip memory device.
