Today’s System-on-Chip typically embeds memory IP cores with very large aggregate bit count per SoC. This trend requires using dedicated resources to increase memory yield, while containing test & repair cost and minimizing time-to-volume. This paper summarizes the evolution of such yield optimization resources, compares their trade-offs, and concentrates on on-chip Infrastructure IP. To maximi...

Trade-offs occur frequently within sociotechnical systems and allow the system to maintain its output in the face of the variable performance of its constituent components. Trade-offs also occur between systems that must interact with each other. Some of these intersystemic tradeoffs may threaten the integrity of one or both systems particularly if the allowable magnitude of the trade-off is no...

Fast time-to-market for mixed-signal ASICs with embedded non-volatile memory (NVM) requires robust IP blocks of different array sizes. This paper describes array topology, design architecture and digital wrapper trade-offs that must be considered in designing a scalable NVM. Specific time generator, sense amplifier and array topology are displayed as well as a BIST specific approach. Finally HI...

Reducing the number of memory accesses is the main goal of the memory field merging. Different cases of dependencies between memory access are described, and trade-offs of field merging, related to the cases of dependencies, are discussed. Optimization guidelines-using collected data about dependencies to analyze effects of field merging-are proposed.

Attention can be attracted faster by emotional relative to neutral information, and memory also can be strengthened for that emotional information. However, within visual scenes, often there is an advantage in memory for central emotional portions at the expense of memory for peripheral background information, called an emotion-induced memory trade-off. The authors examined how aging impacts th...

In 1980, Hellman introduced a time/memory trade-off (TMTO) algorithm satisfying the TMTO curve TM = N, where T is the online time, M is the memory and N is the size of the search space. Later work by Biryukov-Shamir incorporated multiple data to obtain the curve TMD = N, where D is the number of data points. In this paper, we describe a new table structure obtained by combining Hellman’s struct...

Fitness trade-offs across episodes of selection and environments influence life-history evolution and adaptive population divergence. Documenting these trade-offs remains challenging as selection can vary in magnitude and direction through time and space. Here, we evaluate fitness trade-offs at the levels of the whole organism and the quantitative trait locus (QTL) in a multiyear field study of...

The effects of emotion on memory are often described in terms of trade-offs: People often remember central, emotional information at the expense of background details. The present experiment examined the effects of aging and encoding instructions on participants' ability to remember the details of central emotional objects and the backgrounds on which those objects were placed. When young and o...
