Memory Component with Pattern Register Circuitry to Provide Data Patterns for Calibration |
摘要 |
A memory component includes a memory core comprising dynamic random access memory (DRAM) storage cells and a first circuit to receive external commands. The external commands include a read command that specifies transmitting data accessed from the memory core. The memory component also includes a second circuit to transmit data onto an external bus in response to a read command and pattern register circuitry operable during calibration to provide at least a first data pattern and a second data pattern. During the calibration, a selected one of the first data pattern and the second data pattern is transmitted by the second circuit onto the external bus in response to a read command received during the calibration. |
