As described in previous paragraph, both SRAM and DRAM are volatile memory types. As long as power is supplied, the information remains intact; once system power is off, the data cannot be retained thereafter. Compared to DRAM (store information by pumping charges), SRAM does not require peri...
Figure 17.1.4b shows the block diagram of the delay chain for 90 degrees. The detection circuits (DT) compare the phase of clock with that of delayed clock and select a clock path where there is no phase dif- ference between the two clocks. A clock phase shifted by 90...
SRAM (Static RAM) is static RAM. It is also composed of transistors. On represents 1 and off represents 0, and the state remains until a change signal is received. These transistors do not need to be refreshed, but they will lose information like DRAM when they are shut down or powered ...

SRAM is also easier to control (interface to) and generally more truly random access than modern types of DRAM. Due to a more complex internal structure, SRAM is less dense than DRAM and is therefore not used for high-capacity, low-cost applications such as the main memory in personal ...
