Patent number: 9208856Abstract: A multiport SRAM has an array of cells, a first port, and a second port. During a period of different row addresses for the ports, the first port uses first word lines and first bit lines. The second port uses second word lines and second bit lines. In response to the second port switching to the same address as the first port to make a row match, the second port and the first port use the first plurality of word lines, but the first port uses the first plurality of bit lines and the second port uses the second plurality of bit lines. If the row match is removed by the first port changing row addresses, a correlation swap is performed so that the first port performs accesses using the second word lines and bit lines and the second port performs accesses using the first word lines and bit lines.Type: GrantFiled: March 12, 2013Date of Patent: December 8, 2015Assignee: FREESCALE SEMICONDUCTOR, INC.Inventor: Perry H.

Publication number: 20150346272Abstract: An integrated circuit (IC) is connected to an automated test equipment (ATE) with pogo pins. The IC includes an analog-to-digital converter (ADC), a voltage controlled oscillator (VCO), and a compensation circuit. The ATE provides reference voltage signals to the ADC by way of the pogo pins. A potential drop across a pogo pin introduces an error in a reference voltage signal that is reflected in a digital signal generated by the ADC. The VCO generates reference frequency signals corresponding to the reference voltage signals. The compensation circuit receives the reference frequency signals and the digital signal and generates a compensation factor signal. The compensation circuit multiplies the compensation factor signal and the digital signal to generate a compensated digital signal to compensate for the error introduced by the potential drop across the pogo pins.Type: ApplicationFiled: May 27, 2014Publication date: December 3, 2015Applicant: Freescale Semiconductor, Inc.Inventors: Kumar Abhishek, Kushal Kamal, Vandana Sapra
