摘要: A method of reading a dual-bit memory cell includes a controlling terminal, a first terminal, and a second terminal. The dual-bit memory cell has a first bit storage node and a second bit storage node near the first terminal and the second terminal respectively. First, a controlling voltage and a read voltage are applied to the controlling terminal and the first terminal respectively. The second terminal is grounded to measure a first output current value of the first terminal. Then, the controlling voltage and the read voltage are applied to the controlling terminal and the second terminal respectively. The first terminal is grounded to measure a second output current value of the second terminal. Afterward, the bit state of the first bit storage node and the bit state of the second bit storage node is read simultaneously according to the first output current value and the second output current value.

摘要: A flash memory device including a memory array, a row decoder and M page buffers is provided, wherein M is a positive integer. The memory array includes a plurality of memory cells and is electrically connected to a plurality of word lines and a plurality of bit lines. The row decoder drives a specific word line among the word lines during an enabling period. The M page buffers divide the enabling period into N sub-periods, wherein N is an integer greater than 2. Furthermore, the ith, (i+N)th, (i+2N)th, . . . , (i+(M−1)*N)th bit lines are driven by the M page buffers during the ith sub-period, so as to program the memory cells electrically connected to the specific word line, wherein i is an integer and 1≦i≦N.
