Manufacturer:DALLAS Description:2. Using a CAS-before-RAS refresh cycle. CAS-before- RAS refresh is activated by the falling edge of RAS, while holding CAS LOW. In CAS-before-RAS refresh cycle, an internal 10-bit counter provides the row ad- dresses and the external address inputs are ignored. CAS-before-RAS is a refresh-only mode and no data access or device selection is allowed. Thus, the output remains in the High-Z state during the cycle. |
