Abstract: An integrated circuit and method of generating a layout for an integrated circuit in which circuitry peripheral to an array of repetitive features, such as memory or logic cells, is realized according to devices constructed similarly as the cells themselves, in one or more structural levels. The distance over which proximity effects are caused in various levels is determined. Those proximity effect distances determine the number of those features to be repeated outside of and adjacent to the array for each level, within which the peripheral circuitry is constructed to match the construction of the repetitive features in the array.

Abstract: A method of screening complementary metal-oxide-semiconductor CMOS integrated circuits, such as integrated circuits including CMOS static random access memory (SRAM) cells, for n-channel transistors susceptible to transistor characteristic shifts over operating time. For the example of SRAM cells formed of cross-coupled CMOS inverters, static noise margin and writeability (Vtrip) screens are provided. Each of the n-channel transistors in the CMOS SRAM cells are formed within p-wells that are isolated from p-type semiconductor material in peripheral circuitry of the memory and other functions in the integrated circuit. Forward and reverse body node bias voltages are applied to the isolated p-wells of the SRAM cells under test to determine whether such operations as read disturb, or write cycles, disrupt the cells under such bias. Cells that are vulnerable to threshold voltage shift over time can thus be identified.

Abstract: Solid-state random access memory including error correction capability applied to memory arrays entering and exiting a data retention mode. Error correction coding of the data to be retained is performed upon determining that a portion of the memory is to enter data retention mode; the parity bits (i.e., bits in addition to those required for storage of the payload) are stored in available memory cells within or external to the retention domain. Upon exit from retention mode, the code words are decoded to correct any errors, and the payload data are returned to the original cells. Error correction encoding and decoding is not performed in the normal operating mode.

Abstract: Bias circuitry for a static random-access memory (SRAM) with a retain-till-accessed (RTA) mode. The memory is constructed of multiple memory array blocks, each including SRAM cells of the 8-T or 10-T type, with separate read and write data paths. Bias devices are included within each memory array block, for example associated with individual columns, and connected between a reference voltage node for cross-coupled inverters in each memory cell in the associated column or columns, and a ground node. In a normal operating mode, a switch transistor connected in parallel with the bias devices is turned on, so that the ground voltage biases the cross-coupled inverters in each cell. In the RTA mode, the switch transistors are turned off, allowing the bias devices to raise the reference bias to the cross-coupled inverters, reducing power consumed by the cells in that mode.

Abstract: Bias circuitry for a static random-access memory (SRAM) with a retain-till-accessed (RTA) mode. The memory is constructed of multiple memory array blocks, each including SRAM cells formed of array transistors; functional and other circuitry outside of the array are formed of core transistors, constructed differently from the array transistors. Bias devices are included within each memory array block, the bias devices constructed as one or more array transistors. The bias devices for a memory array block may be connected in parallel with one another. In the RTA mode, the bias devices drop the power supply voltage differential across each of the SRAM cells. In a normal operating mode, a core transistor serves as a switch, shorting out the bias devices so that the full power supply differential appears across the SRAM cells.
