Data transmission method for use in memory device e.g. read only memory, involves transmitting data between memory control and interface units, and producing clock signals assigned to data signals in interface units by phase servo loop

摘要

The method involves transmitting data between a memory control (200) and interface units (20), which are attached to memory modules (100a,100b,100c). The units (20) are arranged on same side of mechanically detachable connection (10) as the control. The data is transmitted between the units (20) and module over the connection. Clock signals assigned to the data signals are produced in the interface units by a phase servo loop (250). Independent claims are also included for the following: (1) a memory module for a memory device (2) a device for coupling memory module for data transmission to a memory control over the mechanically detachable connection (3) a memory device with the memory control, memory module and the device for coupling memory module for data transmission to a memory control over the mechanically detachable connection.
