What is CAS?

What is CAS?
To be able to access data from a particular storage area in RAM, the RAS and CAS procedures are needed to provide the address of the storage area. The RAM is organised as an array of storage areas. Each storage area can therefore be uniquely identified by the number of the row and the number of the column that intersect at that position. Row Access Strobe (RAS) is the process of identifying the row from which data needs to be read. This step precedes CAS. Column Access Strobe is the process of identifying the column from which data is to be accessed.
