This report presents a Memory Floorplan Analysis of the Micron Z21C die found inside the Micron MT40A2G4SA-062E:J DDR4 SDRAM component.

This report contains the following detailed information:
  • Selected teardown photographs, package photographs, package X-rays, die markings, and die photographs
  • SEM cross-sectional micrographs of a bevel through the memory array showing the active, bit line (BL) and word line (WL) level plan-view features of the memory array and a cross section through the BL, showing the general structure of the DRAM cell array, dielectric materials, major features, and transistors
  • Measurements of vertical and horizontal dimensions of major microstructural features
  • Plan-view optical micrograph of the die delayered to the polysilicon layer
  • Identification of major functional blocks on a polysilicon die photograph
  • Table of functional block sizes and percentage die utilization
  • High-resolution top metal and diffusion level die photographs delivered in the CircuitVision software
  • Cost of die and tested packaged die, based on the manufacturing cost analysis of the observed process
