摘要： Provided is a bit patterned medium including bridges which induce exchange coupling between adjacent bits in order to reduce a switching field difference resulting from different magnetization directions of bits. The bridges and the bits are integrally formed with each other. The bits are locally connected by the bridges. A magnetostatic force for each bit is reduced due to an exchange coupling between adjacent bits, thereby reducing a switching field distribution of the bits.

摘要： A flash memory system configured in accordance with an example embodiment of the invention employs a virtual ground array architecture. During programming operations, target memory cells are selected and the appropriate programming voltages are established at their wordlines and bitlines. Unselected wordlines in the array are biased with a slight negative bias voltage to reduce or eliminate leakage bitline current that might otherwise conduct through the memory cells. A slight negative wordline bias voltage may also be applied to unselected cells during verification operations (program verify, soft program verify, erase verify) and read operations to reduce or eliminate leakage current that might otherwise introduce errors in the verification and read operations.
