Abstract: A suspendable vacuum storage bag includes a bag body and a suspending device. The bag body has a single opening forming a sealable opening. The suspending device is provided at an end opposite or adjacent to the sealable opening. The sealable opening can be sealed by sealing means after articles are placed flatly inside the bag body. Hangers on which articles are hung can be fastened to a suspending plate of the suspending device to achieve optimum use of available storage space. The bag body can be suspended by means of the suspending device.

Abstract: The method provided first partitions the memory, which has defective cells at unknown locations, into a plurality of frames. Each of the plurality of frames has a corresponding N-bit of cell, and M-bit of cell for storing an index representative of the defectiveness of the (M+N)-bit cell. Secondly, the method performs a predetermined pattern write-read access test to the corresponding (M+N)-bit cell for each frame to determine if the (M+N)-bit of cell is defective. Thirdly, the method stores a first value of the index into the corresponding M-bit of cell for each frame, if the (M+N)-bit cell is good. Fourthly, the method stores a second value of the index into the corresponding M-bit of cell, if the (M+N)-bit cell is defective.
