Q

While troubleshooting a memory problem in a raster scan RADAR, you discover that the "REFRESH" cycle is not operating correctly. What type of memory circuit are you working on?

🔍 Key Concepts

• Difference between static and dynamic memory circuits • How older raster scan RADAR displays store and maintain data on the screen • What a refresh cycle is needed for in certain types of RAM

💭 Think About

• Ask yourself: Which type of memory slowly loses its stored information unless it is periodically refreshed? • Consider which memory type uses tiny capacitors that must be recharged to keep the data valid. • Think about which memory types are mainly for permanent or semi-permanent storage and would not normally need a refresh cycle.

✅ Before You Answer

• Verify which RAM type specifically requires a refresh cycle to maintain data. • Eliminate any memory types that are non-volatile (keep data with no power) from consideration. • Confirm that the memory used in many older raster scan RADAR systems matches the RAM type that relies on periodic refreshing.
