Patent number: 7519766Abstract: A method and a device are described for transmission of control information for the adjustment of operating parameters of drivers in the data interface of a RAM module by means of a controller, with control bits for adjustment purposes being sent during an adjustment mode by the controller as a burst of data bits at the data clock rate to the RAM module. According to the invention, each control bit which is sent from the controller via the data channel in the burst is represented by a sequence of n?2 data bits, which have a binary value corresponding to the relevant control bit and follow one another at the data clock rate. The binary value of each control bit sent via the data channel is determined in the RAM module by detection of the binary value of the sent burst within the relevant sequence at a time at which the m-th data bit in the sequence appears, where m>1.Type: GrantFiled: March 21, 2006Date of Patent: April 14, 2009Assignee: Infineon Technologies AGInventor: Andre Schäfer
