Prospective memory refers to remembering to carry out an intended or planned action, such as keeping a doctor's appointment or telling a friend about an upcoming party. Despite its importance in everyday life, prospective memory has received little empirical or theoretical attention. Rather, much of the literature has focused on retrospective memory, that is, memory for information learnt in the past. The current literature on prospective memory addresses five aspects that are necessary for carrying out an intended action. These are (a) formulating the plan; (b) having the knowledge necessary to carry out the plan; (c) remembering the plan at the appropriate time; (d) carrying out the plan; and (e) remembering that the plan has been performed. The literature also raises three fundamental questions. Namely, whether prospective and retrospective memory involve different processes, whether self-report and behavioral measures of prospective memory are correlated, and whether prospective memory performance varies as a function of age. These questions were the focus of the exploratory studies presented in this dissertation. The first three studies involved the development of a memory diary, a memory questionnaire, and a metamemory questionnaire, respectively. These instruments were used in the fourth and fifth studies. Studies 4 and 5 also included behavioral measures of prospective memory and objective measures of retrospective memory. The fourth study examined how community-dwelling adults feel about, and use, their memory on a daily basis. In accordance with previous research, no age differences were observed on the behavioral measures of prospective memory. Moreover, performance on the self-report measures did not differ as a function of age. As hypothesized, age was correlated with performance on a retrospective memory task. The fifth study involved an extension and replication of Study 4, with the major addition being the use of several standard laboratory tests to assess retrospective memory. This study revealed several interesting findings. First, in contrast to previous studies, performance on some retrospective memory tasks was related to performance on some prospective memory tasks. Second, by and large, self-report and behavioral measures of prospective memory were not correlated. Third, performance on the prospective memory tasks (both self-report and behavioral) did not vary as a function of age, although performance ' on the retrospective memory tasks was clearly age related. The implications of this research are discussed. / Arts, Faculty of / Psychology, Department of / Graduate

Recognition memory for complex pictures was investigated using 3 variables: meaningf ulness of the target (anomalous or conventional), type of transformation in the distractor (substitution or rearrangement), and extent of transformation (whether the target and distractor were consistent or inconsistent in meaningf ulness) . Three- and four- year olds were familiarized with 16 different thematic scenes with which a child this age would likely have had experience. Half of the target pictures shown to a child were conventional, and half were anomalous, containing either an object or arrangement of objects that did not fit the theme. During the recognition test, targets were paired with distractors that were either conventional or anomalous (yielding the consistent-inconsistent conditions) and contained either a substitution of one object or a rearrangement of objects. Overall, recognition memory was similar for conventional and anomalous targets indicating that both types of pictures were assimilated into schemata equally well. When target and distractor were inconsistent in meaningfulness, recognition memory was facilitated. Thus, information about whether the target contained an anomaly or not was remembered.

In system-on-chip designs, memory designs store data to be accessed by processing modules. Memory access time can affect overall system performance significantly. In this research, we implemented a configurable architecture of a basic memory module and its design composition, including memory interface, memory controller, memory array, row buffer, row decoder and column decoder. We explore various memory module designs. Utilizing the configurable architecture, we can effectively reduce design time and improve access time of memory module designs. We also realized these functionalities in SystemC language and performed configurability experiments.

The advent of many core architectures has coincided with the energy and power limited design of modern processors. Projections for main memory clearly show widening of the processor-memory gap. Cache capacity increased to help reduce this gap will lead to increased energy and area usage and due to small growth in die size, impede performance scaling that has accompanied Moore's Law to date. Among the dominant sources of energy consumption is the on-chip memory hierar- chy, specically the L2 cache and the Last Level Cache (LLC). This work explores the use of a novel non-volatile memory technology - Spin Torque Transfer RAM (STT RAM)" for the design of the L2/LLC caches. While STTRAM is a promising memory technology, it has some limitations, particularly in terms of write energy and write latencies. The main objectives of this thesis is to use a novel cell design for a non-volatile 1T1MTJ cell and demonstrate its use at the L2 and LLC cache levels with architectural optimizations to maximize energy reduction. The proposed cache hierarchy dissipates significantly lesser energy (both leakage and dynamic) and uses less area in comparison to a conventional SRAM based cache designs.
