Using the Internet, fi nd a data sheet for a DRAM chip. Can you determine the relationship between the number of address lines and the number of addresses?
What will be an ideal response?
DRAM datasheets, such as for the Micron MT46V128M4BN, are detailed and complex. However, a direct relationship exists between the number of data pins and the chip’s word size. If the chip has a word size of 4 bits, there will be 4 data lines. Data lines are labeled DQ0-DQ3, for instance. The number of address bits on DRAM chips is fewer than the number of address lines needed because addressing information is obtained in two steps for DRAM. This multiplexed addressing scheme limits the number of addressing lines needed.
