Practical Design and Implementation of VLSI Memory Devices | VLSI.X417

Practical Design and Implementation of VLSI Memory Devices | VLSI.X417

This course for new and mid-hires in the custom memory design sector reviews key technologies in VLSI design such as CMOS (complementary metal-oxide-semiconductor), and FinFET (fin field-effect) transistors, NMOS (N-type metal oxide semiconductor) transfer curve and the derivation of MOS (metal-oxide-semiconductor) current across different regions of operation.

Students in this course will learn basic memory operation and principles, discuss various tools used for verification of memories, how these tools are used, how practical compiler SRAMs are built in industry, and how they are verified. By focusing on memories and tools related to verification of memories, students go from ground zero to designing and verifying memories on the job.

The class will analyze the 6T bitcell, study of bitcell stability, typical SRAM architecture and move into a detailed discussion on the decoder architecture, sense amplifier architecture and operation, and exploration of IO architectures.

We will dive into the details of the read/write timing waveforms, and timing analysis of memories using Hspice and Nanotime and discuss other verification tools such as ESPCV (logical equivalence), and fanout and noise tools. We will see how analysis corners are derived, and how memories get characterized and analyzed across these corners. Then we will discuss how compiler memories are designed and what factors go into consideration of selecting the number of entries, bits and mux (multiplexer) factors.

We will go into types of bitcells, how multi-ported and multi-banked memories are designed, and what are the pros and cons of each style.
