Publication number: 20170005662Abstract: Methods and apparatus for providing either high-speed, Or lower-speed, flexible inputs and outputs. An input and output structure having a high-speed input, a high-speed output, a low or moderate speed input, and an low or moderate speed output is provided. One of the input and output circuits are selected and the others are deselected. The high-speed input and output circuits are comparatively simple, in one example having only a clear signal for a control line input, and are able to interface to lower speed circuitry inside the core of an integrated circuit. The low or moderate speed input and output circuits are more flexible, for example, having preset, enable, and clear as control line inputs, and are able to support JTAG boundary testing. These parallel high and lower speed circuits are user selectable such that the input Output structure is optimized between speed and functionality depending on the requirements of the application.Type: ApplicationFiled: September 16, 2016Publication date: January 5, 2017Inventors: Bonnie I. Wang, Chiakang Sung, Joseph Huang, Khai Q. Nguyen, Philip Y. Pan

Patent number: 6992947Abstract: Methods and apparatus for a dual-port SRAM in a programmable logic device. One embodiment provides a programmable logic integrated circuit including a dual-port memory. The memory includes a plurality of memory storage cells, and each memory storage cell has a memory cell having a first node and a second node, a first series of devices connected between a first data line and the first node of the memory cell, and a second series of devices connected between a second data line and the second node of the memory cell. A read cell is connected to the second node of the memory cell. A word line is connected to a first device in the first series of devices, a second device in the second series of devices, and the read cell.Type: GrantFiled: October 28, 2003Date of Patent: January 31, 2006Assignee: Altera CorporationInventors: Philip Y.

Patent number: 6747903Abstract: Methods and apparatus for decoding addresses in a memory to provide mixed input and output data widths. A method includes receiving an address portion comprising a first number of bits. A second number of bits of the address portion are blocked, where the second number is less than the first number. A third number of bits are not blocked, and the third number plus the second number equal the first number. The third number of bits are decoded and a fourth number of memory cells are selected. The fourth number is equal to two to the power of the second number. A fourth number of data bits are received and multiplexed to the selected memory cells. The data bits are written to the selected memory cells.Type: GrantFiled: January 14, 2002Date of Patent: June 8, 2004Assignee: Altera CorporationInventors: Philip Y.
