    摘要: Non volatile memories and methods of programming thereof are disclosed. In one embodiment, the method of programming a memory array includes receiving a series of data blocks, each data block having a number of bits that are to be programmed, determining the number of bits that are to be programmed in a first data block, determining the number of bits that are to be programmed in a second data block, and writing the first data block and the second data block into the memory array in parallel if the sum of the number of bits that are to be programmed in the first data block and the second data block is not greater than a maximum value. The first and second data blocks may or may not be adjacent data blocks. Improved programming efficiency may be achieved in a memory circuit when the maximum allowable current may be limited by the application or the size of a charge pump. Inverse data may be written in parallel if the sum is greater than the maximum value.
