Scope
We are seeking an experienced Memory Design Engineer to work on the architecture, design, compiler development, characterization, and silicon validation of embedded SRAM and Register File (RF) IPs for ultra-low-power SoCs. The ideal candidate will possess strong expertise in SRAM compiler development, custom memory circuit design, timing and power characterization, silicon correlation, and production-quality memory IP delivery. This role requires close collaboration with architecture, physical design, product engineering, foundry, EDA vendors, and silicon validation teams to develop highly optimized embedded memories operating across conventional, near-threshold, and sub-threshold voltage ranges. This role is critical in ensuring robust memory operation across extreme low-voltage conditions, aligned with Ambiq SPOT principles.
Responsibilities
Design ultra-low power embedded SRAM and Register File IPs for advanced SoC products.
Develop and enhance SRAM compiler architectures supporting multiple memory configurations, banking schemes and redundancy options.
Design and optimize memory peripheral circuits such as sense amplifiers, write drivers, decoders, word-line drivers, pre-charge circuits, Read/write assist circuits, redundancy and repair logic
Optimize memory designs for Area, Performance, Leakage power, Dynamic power, yield and manufacturability. Correlate simulation and characterization results with silicon measurements and production test data.
Analyze low-voltage failure mechanisms including read disturb, write failure, read/write margins, retention failures and process variation effects
Drive memory yield improvement through silicon debug, characterization analysis, and design optimization.
Develop automation scripts using Python, Tcl, or Perl to improve compiler generation, characterization efficiency, regression, and design productivity.
Collaborate with Memory architecture teams, Physical design, Timing and STA teams, DFT/BIST engineers, Product and test engineering, Foundry partners and EDA vendors
Support memory IP integration into SoC products from architecture through production release.
Document methodologies, design guidelines, characterization results, and silicon learnings.
Qualifications
Bachelor’s, Master’s, or PhD in Electrical Engineering, Electronics, or related discipline.
Strong understanding of SRAM architecture, compiler design, and custom memory circuit design.
Proven experience developing embedded SRAM or Register File IP for advanced 12nm FINFET technologies and below.
Hands-on experience with SRAM compiler development and configurable memory generation.
Strong expertise in custom memory characterization and production-quality Liberty (.lib) generation.
Deep knowledge of bit-cell operation, sense amplifier design, read/write assist techniques, low-voltage SRAM operation, process variation analysis, timing and power characterization
Experience with Cadence Virtuoso, Spectre, HSPICE or equivalent SPICE simulators, Cadence Liberate MX and Monte Carlo simulations
Familiarity with memory compiler architecture and IP delivery flows.
Experience supporting silicon bring-up, characterization, debug, and production qualification.
Knowledge of memory redundancy, repair algorithms, ECC, and MBIST integration is highly desirable.
Strong scripting skills in Python, Tcl, Perl, or equivalent programming languages.
Excellent analytical, debugging, communication, and cross-functional collaboration skills.
