Memories are most important building blocks in many digital systems. As the Integrated Circuits requirements are growing, the test circuitry must grow as well. There is a need for more efficient test techniques with low power and high speed. Many Memory Built in Self-Test techniques have been proposed to test memories. Compared with combinational and sequential circuits memory testing utilizes ...

The design and architecture of a memory test synthesis framework for automatic generation, insertion and veriication of memory BIST units is presented. We use a building block architecture which results in full customization of memory BIST units. The exibility and eeciency of the framework are demonstrated by showing that memory BIST units with diierent architecture and characteristics could be...

Input vector monitoring concurrent BIST schemes are the class of online BIST techniques that overcomes the problems appearing separately in online and in offline BIST in a very effective way. This paper briefly presents an input vector monitoring concurrent BIST scheme, which monitors a set of vectors called window of vectors reaching the circuit inputs during normal operation, and the use of a...

3⁄4 In order to accomplish a high speed test on low speed Automatic Test Equipment (ATE), a new instruction based, fully programmable memory, Built-in Self-Test (BIST) is proposed. The proposed memory BIST generates a high speed internal clock signal by multiplying the external low speed clock signal from the ATE. For maximum programmability and small area overhead, the proposed BIST receives t...

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...

ghorban tower as an architectural monument is one of the outstanding resting- place of islamic era in hamadan city which has not been studied properly. previous studies on the tower concerning its architectural features or its historical background showed that the tower may be a place where a dignified religious man named khajeh hafez abol'ala hamadani berried inside in saljuk era and afte...
