Embedded Memories in System Design: Technology, Application, Design and Tools

چکیده
First, background will be provided on embedded DRAM process, circuit and market issues. The term system-on-silicon has been used to denote the integration of random logic, processor cores, SRAMs, ROMs, and analog components on the same die. But up to recently, one major component had been missing: high-density DRAMs. Today's technologies allow the integration of significant amounts of DRAM memory for applications such as data buffering, picture storage, and program/data storage. In quarter-micron technology, chips with up to 128 Mbit of DRAM and 500 kgates of logic are eminently feasible. This enlarges the system design space tremendously since system architects are no more restricted to standard commodity DRAMs. We will discuss the market for embedded DRAM applications as well as the associated challenges.

Embedded Memory Test Strategies and Repair
The demand of self-testing proportionally increases with memory size in System on Chip (SoC). SoC architecture normally occupies the majority of its area by memories. Due to increase in density of embedded memories, there is a need of self-testing mechanism in SoC design. Therefore, this research study focuses on this problem and introduces a smooth solution for self-testing. In the proposed m...

متن کاملTowards Application-Specific Architecture Platforms: Embedded Systems Design Automation Technologies
Architectural platforms can be defined as a domainor application-specific base design which is easily configured to the specific needs of a given market. This configuration can be done before fabrication, i.e. at the design level, supported by hardware configuration and synthesis tools. The configuration can also be done after chip fabrication, by programming portions of logic on the chip imple...
متن کاملRIG: Targeting Designs with Embedded Memories to ASIC and FPGA Technologies
A chip design, that uses individual technology specific macros or cells, is incompatible to alternative target technologies. This prevents most designs containing such macros or cells from being reused in a different technology, even if the logic part surrounding the macro can be easily retargeted. However, avoiding these technology specific macros in a reusable design is not always possible. E...
