How many ram chips of 256kb required to realize 1 GB?
A hypothetical 32x1 RAM chip provides storage for 32 bits or 4 bytes. 256k bytes require 256 * 1000 * 8 = 2048000 bits (or 256 * 1024 * 8 = 2097152 bits, if the k is interpreted to mean kibibyte rather than kilobyte, using the IEC nomenclature).Because 2048000 / 32 = 64000, you'd need 64000 chips.
