A line in a memory that selects which word (and its associated bit cellsA cell that stores a single bit within a memory. (Some can store more than one bit.) It connects a word line to a bit line. The bit cell can either conduct or not conduct current; those are the two states of the memory cell.) will be selected for reading or writing, based on the memory addressWhen referring to memory, a binary number that shows where, within some memory block, the data you want is located. If you want to read or change that data, you have to give the address so that the right data is read or changed.. The word lines and bitThe smallest unit of information. It is a shortened form of "binary digit." Since it's binary, it can have only two values -- typically 0 and 1. lines are orthogonalAt right angles (or 90°) to something else. More generally, two settings or properties that you can set independently of each other are said to be orthogonal. to each other, making an array of the bit cells that connect them.
