Hi blake_paterson; Re Rambus' patent on adjustable latency for memory chips... I believe that the oldest of the Rambus patents that mentions adjustable latency in memory is 5319755, which was filed Sept 30, 1992, and issued June 7, 1994: Under claims: 23. The apparatus of claim 22 for storing and retrieving data, further comprising means for the master to request the first memory to prepare for a bus transaction by sending a request packet along the bus, wherein the first memory and the master each includes (1) a means for initiating an internal phase for preparing a bus access phase of the bus transaction and (2) a bus access means to effect the bus transaction during the bus access phase, wherein the request packet comprises a sequence of bytes containing first control information and a first address, wherein the first control information includes information about the requested bus transaction and about an access time, wherein the access time corresponds to a number of bus cycles that must intervene before beginning the bus access phase, and wherein the first address points to a memory location within the discrete memory section of the first memory. patents.ibm.com Any comments from the engineers? -- Carl
