Help Needed: Testing HM6116 SRAM Chip on ATE Platform

Hello everyone,

I am currently working on testing the HM6116 SRAM chip as part of my project, and I am seeking guidance on how to properly conduct its testing on an ATE platform provided by my school. The testing process is divided into three parts: DC parameter testing, AC parameter testing, and circuit functionality verification.

So far, I have gathered some understanding of verifying the chip's read and write functionality, but since this chip is relatively old and I am not very familiar with SRAM chips, I am struggling with how to conduct DC parameter testing and AC parameter testing. Additionally, while I have access to the chip's datasheet, I am unsure which parts of it are most relevant to designing and performing the experiments.

Here is a brief overview of my situation:

• DC parameter testing: I understand that this involves measuring properties like input/output leakage current, standby current, and operating current. However, I am not sure how to configure the ATE system to measure these parameters or what test signals and conditions are required.
• AC parameter testing: I need to evaluate timing characteristics like read/write cycle times, access times, and setup/hold times. I am unclear on how to apply and measure these signals using the ATE system, especially given the specific timing requirements of the HM6116.
• Functional testing: I have already learned some basic read/write operation testing, but additional tips on verifying complete functionality would be appreciated.

If anyone has experience testing SRAM chips like the HM6116 or using ATE platforms for similar purposes, I would greatly appreciate your advice on:

1. How to set up the ATE platform for DC and AC parameter testing.
2. Which parts of the datasheet are most relevant to designing my experiments?
3. Any specific tools or techniques that could simplify the process.
4. Suggestions for interpreting results and ensuring accuracy.

Thank you in advance for your help! I look forward to hearing your insights.

Best regards,

Morgan
