Learning Objectives

  • Memory can be classified into inboard and outboard memory with varied accessibility and speeds.

  • Access time and transfer rates are critical parameters that influence memory performance and selection.

  • Different memory technologies, like SRAM and DRAM, exhibit distinct trade-offs between speed and cost.

Key Concepts

Access Time

The time it takes for a memory system to retrieve data after a request.

Transfer Rate

The speed at which data can be read from or written to memory, measured in bits per second.

Volatile Memory

Memory that loses stored information when the power is turned off, such as RAM.

Nonvolatile Memory

Memory that retains stored information even when not powered, such as ROM and flash memory.

Unit of Transfer

The amount of data (measured in bits) that can be transferred between memory and the CPU in a single operation.
