According to wikipedia, the delay line memory is considered to be “refreshable.” This means that it consistently process information from different aspects of the computer and is able to rewrite the process information in the same area with adjustments being made. Delay line is also serial access meaning it is capable of data memory array is accessed in a sequential order that is predetermine. The alternative method was a random access. The random access memory contrasts from delay line memory. The random line access stores data and once accessed it returned the information in any order, not necessarily the order one puts it in. I consider random access a less organized system. Some devices and products that uses DRAM are digital audio players, digital cameras, PCs, and mobile phones.
