Custom Memory Design Engineer

As a Custom Memory Design Engineer, you will build the custom memories that power our unconventional computing architecture. You will design unique RAM circuits in various RAM technologies, including SRAMs and DRAMs to support a unique computational architecture. Working alongside silicon architecture, digital design, memory architects, and analog design engineers, you will own the end-to-end development of various RAM circuits, from clean-sheet design through closure and tapeout, and silicon bring-up, unlocking unprecedented throughput-per-watt.

Responsibilities

Lead the full custom RAM development cycle, from architecture, establishing methodology, tooling, design, to closure; Develop or acquire RAM IP for use in Normal Silicon, including RAM PDKs; Acquire or help direct RAM design EDA tool development; Design unique RAM circuits in various RAM technologies, including SRAMs and DRAMs; Own the end-to-end development of various RAM circuits, from clean-sheet design through closure and tapeout, and silicon bring-up

Requirements

Developed RAM IP from spec to GDSII in modern technologies, taped out and brought up; Worked on memory technologies (i.e. SRAM, DRAM) at the core level (bitcell arrays and peripheral circuits); Designed and characterized custom bitcells in schematic and layout; Fluent in the Cadence flow: Virtuoso, Spectre, Assembler, Extraction, Layout, HSMC, Characterization; Deep understanding of noise and variation and their impacts on silicon performance and reliability

Nice to have

Lead, taped out, brought up CIM chips; Experienced and comfortable in a chip measurement environment for debug and characterization; Have used AI and/or scripting languages (i.e. Python, Perl) to automate design flows and data post-processing
