Main Memory

In this chapter, we will cover the modern memory design and operations in memory chips and modules that enable efficient data transfer between the memory controller and the so-called DIMMs, i.e., memory modules used in modern computer systems. To fully understand the organization and operation of modern memory chips, we need to start with some fundamental digital building blocks. Then, we gradually build memory components, arrays, operations inside the memory chips, timings, and techniques to boost the performance of memory chips. At the end of the chapter, you should fully understand modern DDR SDRAM chips, DDR memory technology, memory timings, DIMM modules, and multi-channel architecture.
