20100085804 | SEMICONDUCTOR MEMORY DEVICE AND DATA PROCESSING SYSTEM INCLUDING THE SAME - In synchronism with an active command, a row address and a column address are simultaneously received, and a page address is received in synchronism with a read command or a write command. Word drivers select a word line based on the row address, and column switches select a bit line based on the column address. A page address decoder selects any one of read/write amplifiers corresponding to each page based on the page address. With this configuration, a specification for a DRAM such as an access cycle can be satisfied without arranging an amplifier for each bit line, and thus it becomes possible to secure a compatibility with a DRAM while reducing a chip area. | 04-08-2010 |
