How many individual memory cells are in an IC with 4 data bus I/O pins and 4 address pins?

• A. 16
• B. 32
• C. 64
• D. 128

Answer: (C)

To determine the number of individual memory cells in an integrated circuit (IC) with 4 data bus I/O pins and 4 address pins, you can use the relationship between the number of address lines and the number of memory cells that can be addressed. Each address pin can represent two states (0 or 1), which leads to the ability to address a specific number of memory locations. With 4 address pins, the total number of unique addresses can be calculated as \(2^n\), where \(n\) is the number of address pins. In this case, \(n\) is 4, so: \[ 2^4 = 16 \] This means that there are 16 unique addresses in total. Since each memory cell corresponds to one of these addresses, and considering that the data bus has 4 I/O pins, which allows the IC to transfer 4 bits of data at a time, each addressable location can hold a 4-bit word. Therefore, there are 16 memory cells, each capable of holding 4 bits, leading to a clear understanding that there are indeed a total of 16 individual memory cells in this configuration. The reasoning demonstrates that while 4 address lines provide
