MEMORY DEVICE, METHOD OF PERFORMING READ OR WRITE OPERATION AND MEMORY SYSTEM INCLUDING THE SAME

摘要

PURPOSE: A read or write operation method of a memory cell, an apparatus, and a memory system including the same are provided to improve the speed of write and read operations by quickening data as much as the writing speed of DRAM in a write operation and opening a page as the DRAM in a read operation. CONSTITUTION: A first switch(100) transmits data and selects a memory column. A second switch(300) is directly connected to a memory cell for data transmission and memory column selection. A sensing and storage circuit(200) is located between the first switch and the second switch and amplifies and stores the data. The memory cell is composed of resistive memory cells.
