Publication number: 20020196064Abstract: A new D-type latch structure is disclosed which has an input data sampling circuit and a symmetrical cross coupled latching circuit. The clock is delayed a predetermined time through an inverter circuit. The clock and the delayed inverted clock are used to generate a clock window time during which time the data input state and the inverted data input state are asserted on the latch output and complementary. The latch outputs are cross-coupled to pull-up and pull-down circuitry in each output circuit stage. A common pull-down transistor may be used to further reduce devices and to improve path delays from clocks to the latch outputs. The clock window assertion of states of the data inputs to the changing latch output is enhanced by the cross-coupled feedback of the latch outputs to improve the differential transition timings of the latch outputs. The D-type latch has fewer transistors and better delay, and more precise transition skew over prior art designs.Type: ApplicationFiled: May 14, 2002Publication date: December 26, 2002Applicant: IBM CorporationInventors: Nobuo Kojima, Huajun Wen

Patent number: 6356990Abstract: A set-associative cache memory having a built-in set prediction array is disclosed. The cache memory can be accessed via an effective address having a tag field, a line index field, and a byte field. The cache memory includes a directory, a memory array, a translation lookaside buffer, and a set prediction array. The memory array is associated with the directory such that each tag entry within the directory corresponds to a cache line within the memory array. In response to a cache access by an effective address, the translation lookaside buffer determines whether or not the data associated with the effective address is stored within the memory array. The set prediction array is built-in within the memory array such that an access to a line entry within the set prediction array can be performed in a same access cycle as an access to a cache line within the memory array.Type: GrantFiled: February 2, 2000Date of Patent: March 12, 2002Assignee: International Business Machines CorporationInventors: Naoaki Aoki, Sang Hoo Dhong, Nobuo Kojima, Joel Abraham Silberman
