You are selecting RAM for a new PC. You are very concerned about making sure errors are handled. Which of the following types of RAM should you select?

Question

Options

• ARamBus
• BNon Parity RAM
• CECC RAM
• DLogic Parity RAM

• A
  5% (3)
• B
  14% (8)
• C
  71% (40)
• D
  9% (5)

Explanation

Parity RAM can indeed handle error correction, however is not supported in most new computers. ECC is supported. What is ECC memory module? An Error Correcting Code (ECC) memory module detects and corrects single-bit errors in memory. It helps a computer to continue working without interruption and data corruption. Although ECC can detect both single-bit and double-bit errors, it can only correct single-bit errors. As most memory errors are of a single-bit nature, ECC provides high system reliability and attendant availability. An ECC-based computer is a good choice for servers. Answer option B is incorrect. Non parity RAM offers no error checking at all. Answer option D is incorrect. Logic Parity is a mechanism whereby a non parity RAM chip can simulate parity. Answer option A is incorrect. Rambus is unrelated to the issue of parity. What is RIMM? Rambus Inline Memory Module (RIMM) is a type of memory that has 184 pins. It was developed by Rambus, Intel, and Kingston. This module only supports Rambus memory and fits on its own slot.
