What are the two common basic types of RAM? Describe each type in detail.
What will be an ideal response?
Student responses will vary, but should be drawn from the following information from the text.
Two common types of RAM are dynamic RAM and static RAM:
• Dynamic RAM (DRAM pronounced DEE-ram) chips must be reenergized constantly or they lose their contents. Many variations of DRAM chips exist, most of which are faster than the basic DRAM.
• Static RAM (SRAM pronounced ESS-ram) chips are faster and more reliable than any variation of DRAM chips. These chips do not have to be reenergized as often as DRAM chips; hence, the term, static. SRAM chips, however, are much more expensive than DRAM chips. Special applications such as cache use SRAM chips.
