  • Error Detection and Correction Methods for Memories Used in System-On-Chip Designs
    International Journal of Engineering and Advanced Technology (IJEAT) ISSN: 2249 – 8958, Volume-8, Issue-2S2, January 2019 Error Detection and Correction Methods for Memories used in System-on-Chip Designs Gunduru Swathi Lakshmi, Neelima K, C. Subhas ABSTRACT— Memory is the basic necessity in any SoC Static Random Access Memory (SRAM): It design. Memories are classified into single port memory and consists of a latch or flipflop to store each bit of multiport memory. Multiport memory has ability to source more memory and it does not required any refresh efficient execution of operation and high speed performance operation. SRAM is mostly used in cache memory when compared to single port. Testing of semiconductor memories is increasing because of high density of current in the and in hand-held devices. It has advantages like chips. Due to increase in embedded on chip memory and memory high speed and low power consumption. It has density, the number of faults grow exponentially. Error detection drawback like complex structure and expensive. works on concept of redundancy where extra bits are added for So, it is not used for high capacity applications. original data to detect the error bits. Error correction is done in Read Only Memory (ROM): It is a non-volatile memory. two forms: one is receiver itself corrects the data and other is It can only access data but cannot modify data. It is of low receiver sends the error bits to sender through feedback. Error detection and correction can be done in two ways. One is Single cost. Some applications of ROM are scanners, ID cards, Fax bit and other is multiple bit.

  • Introduction to Advanced Semiconductor Memories
    CHAPTER 1 INTRODUCTION TO ADVANCED SEMICONDUCTOR MEMORIES 1.1. SEMICONDUCTOR MEMORIES OVERVIEW The goal of Advanced Semiconductor Memories is to complement the material already covered in Semiconductor Memories. The earlier book covered the fol- lowing topics: random access memory technologies (SRAMs and DRAMs) and their application to specific architectures; nonvolatile technologies such as the read-only memories (ROMs), programmable read-only memories (PROMs), and erasable PROMs in both ultraviolet erasable (UVPROM) and electrically erasable (EEPROM) versions; memory fault modeling and testing; memory design for testability and fault tolerance; semiconductor memory reliability; semiconductor memories radiation effects; advanced memory technologies; and high-density memory packaging technologies [1]. This section provides a general overview of the semiconductor memories topics that are covered in Semiconductor Memories. In the last three decades of semiconductor memories' phenomenal growth, the DRAMs have been the largest volume volatile memory produced for use as main computer memories because of their high density and low cost per bit advantage. SRAM densities have generally lagged a generation behind the DRAM. However, the SRAMs offer low-power consumption and high-per- formance features, which makes them practical alternatives to the DRAMs. Nowadays, a vast majority of SRAMs are being fabricated in the NMOS and CMOS technologies (and a combination of two technologies, also referred to as the mixed-MOS) for commodity SRAMs. 1 2 INTRODUCTION TO ADVANCED SEMICONDUCTOR MEMORIES MOS Memory Market ($M) Non-Memory IC Market ($M) Memory % of Total IC Market 300,000 40% 250,000 30% 200,00U "o Q 15 150,000 20% 2 </> a. o 100,000 2 10% 50,000 0 0% 96 97 98 99 00 01* 02* 03* 04* 05* MOS Memory Market ($M) 36,019 29,335 22,994 32,288 49,112 51,646 56,541 70,958 94,541 132,007 Non-Memory IC Market ($M) 78,923 90,198 86,078 97,930 126,551 135,969 148,512 172,396 207,430 262,172 Memory % of Total IC Market 31% .

Security primitives based on Dynamic Random Access Memory (DRAM) can provide cost-efficient and practical security solutions, especially for resource-constrained devices, such as hardware used in the Internet of Things (IoT), as DRAMs are an intrinsic part of most contemporary computer systems. In this work, we present a comprehensive overview of the literature regarding DRAM-based security primitives and an extended classification of it, based on a number of different criteria. In particular, first, we demonstrate the way in which DRAMs work and present the characteristics being exploited for the implementation of security primitives. Then, we introduce the primitives that can be implemented using DRAM, namely Physical Unclonable Functions (PUFs) and True Random Number Generators (TRNGs), and present the applications of each of the two types of DRAM-based security primitives.

  • Memory Design: System on Chip and Board Based Systems
    Chapter 4 Memory Design: System on Chip and Board based systems 4.1 Introduction Memory design is the key to system design. The memory system is often the most costly (in terms of area or dies) part of the system and it largely determines the perfor- mance. Regardless of the processors and the interconnect, the application cannot be executed any faster than the memory system, which provides the instructions and the operands. Memory design involves a number of considerations. The primary consideration is the application requirements: the operating system, the size and the variability of the ap- plication processes. This largely determines the size of memory and how the memory will be addressed: real or virtual. Figure 4.1 is an outline for memory design, while Table 4.1 compares the area for different memory technologies. We start by looking at issues in SOC external and internal memories. We then examine scratchpad and cache memory to understand how they operate, and how they are de- signed. After that we consider the main memory problem, first the on-die memory and then the conventional DRAM design. As part of the design of large memory systems, we look at multiple memory modules, interleaving and memory system performance. Table 4.2 shows the types of memory that can be integrated into an SOC design. Memory technology Rbe kB per unit A DRAM 0.05 to 0.1 1,800 – 3,600 SRAM 0.6 300 ROM/PROM 0.2 to 0.8+ 225 – 900 eDRAM 0.15 1,200 flash: NAND 0.02 10,000 Table 4.1 Area comparison for different memory technology.
