Study Notes
Computer Memory Organization and Operations
- A number such as 753 requires at least two bytes of storage.
- Word size is processor dependent and is normally in multiples of 8, such as 8, 16, 32, or 64 bits.
- Memory is built from millions of storage cells organized as an indexed array of words, with each word assigned a location number called the word address.
- Memory size can be interpreted in different ways, such as the total memory size being 96 bits, which can be 96 memory words each of size one bit, or 12 memory words each of size 8 bits, and so on.
- Memory operations require data, address, and operation control, typically involving read and write operations.
- A memory chip has three sets of pins: address pins, data pins, and control pins for memory operations.
- The number of address pins, data pins, and the memory total size can be calculated based on the number of words and the size of each word in bits.
- For a memory with 3 address bits and 8 data bits, there are 8 words and each word is of size 8 bits.
- For a memory chip of size 512K x 8, there are 512 KB = 29 * 210 = 219 bits, with 3 control pins, and the size of MDR is 8 and the size of MAR is 19.
- In a 2K x 10 Memory, there are 11 address pins, 10 data pins, and the memory total size is 20480 bits, with MDR size of 10 bits and MAR size of 11 bits.
- The memory is connected to the processor by address, data, and control lines, with the address lines connected to the MAR and the data lines connected to the MDR.
- Read and write operations involve the CPU placing the address of the memory word to be retrieved or written into the MAR register, setting the read or write control, and the memory responding accordingly.
