What information does the cas give to the microprocessor unit?

Answer 1

The CAS (Column Address Strobe) signal informs the microprocessor which specific column in a memory module should be accessed for reading or writing data. It works in conjunction with the RAS (Row Address Strobe) signal, which identifies the row to access. Together, these signals enable the microprocessor to retrieve data from the correct location in dynamic RAM (DRAM) by specifying both row and column addresses. This helps facilitate efficient data management in memory operations.
