Abstract
A storage medium including a plurality of memory cells, a plurality of transmission lines, a driving module and a floating detection module is disclosed. The memory cells store data. The transmission lines are coupled to the memory cells. The driving module accesses the memory cells via the transmission lines. The floating detection module includes a reset unit, a plurality of connectors and a detector. The reset unit is coupled to a detection line. Each of the connectors is coupled between one of the transmission lines and the detection line. The detector determines whether a state of at least one of the transmission lines is a floating state according to a level of the detection line.
Claims15
A storage medium, comprising:
- a plurality of memory cells storing data;
- a plurality of transmission lines coupled to the memory cells;
- a driving module accessing the memory cells via the transmission lines;
- and
- a floating detection module comprising:
- a reset unit coupled to a detection line;
- a plurality of connectors, each coupled between one of the transmission lines and the detection line;
- and
- a detector determining whether at least one of the transmission lines is abnormal according to a level of the detection line during a first detection period, wherein the driving module does not trigger the transmission lines during the first detection period.
A floating detection method for a storage medium comprising a plurality of memory cells, a plurality of transmission lines, a driving module and a floating detection module, wherein the driving module accesses the memory cells via the transmission lines, and the transmission lines are coupled to a detection line via a plurality of connectors, comprising:
- setting a level of the detection line during a reset period;
- and
- determining whether the level of the detection line matches a pre-determined level during a detection period, wherein when the level of the detection line does not match the pre-determined level, it is determined that at least one of the transmission lines is abnormal, wherein the driving module does not trigger the transmission lines during the detection period.
