Flash Memory Interposers | Nexus Technology, Inc.

Interposers

Flash memory technologies are defined by the Open NAND Flash Interface (ONFI) industry workgroup and Joint Electronic Devices Engineering Council (JEDEC) for use in handheld devices or applications where low-power and small size is critical.

Nexus Technology offers high quality and high fidelity interposers, enabling the industry to confidently and accurately gain access to Flash memory buses for debug and compliance verification. … more…

More Information on Interposer Types

Electrical Analysis

Electrical analysis is enabled by using either an EdgeProbe, High Density, or Socketed interposer to capture memory activity on an oscilloscope. The oscilloscope is then used to debug, analyze, and verify the analog characteristics of your design. Presenting an accurate representation of the signals under test to the oscilloscope is critical. Nexus interposers provide an unobtrusive interconnect and accurate signal to your oscilloscope. Learn more…

Logic / Compliance Analysis

Logic analysis is performed using a logic / compliance interposer to capture memory activity on a logic or memory analyzer. The logic or memory analyzer is then used to debug, analyze, and verify the logic (basic protocol) of your design. Compliance analysis uses the same interposers to capture activity on a memory analyzer. The memory analyzer is then used to debug, analyze, margin test, performance analyze, and verify the memory protocol. Learn more…
