Understanding RAM Chips

What are RAM Chips? Random Access Memory (RAM) is a type of volatile memory used to store data that a computer needs to use temporarily. In this context, we have 16K by 4-bit RAM chips, which can each hold 16,384 (or 16K) data using 4-bit (4 data lines).

Connecting Two 16K by 4-bit RAM Chips

To combine two 16K by 4-bit RAM chips into a single 16K by 8-bit memory module, we need to manage the arrangement of data, address lines, and control signals effectively. Here’s a detailed explanation and a diagrammatic representation.

1. Address Lines

The 16K x 4 memory cells in the chips are addressed using 14 address lines (A0-A13). In the 16K x 8 module, these same 14 address lines (A0-A13) will control the access to the combined memory space. No address lines need to be added or subtracted as they remain the same.

2. Data Lines

The essential step is connecting the data lines of the two 16K by 4-bit RAM chips to form an 8-bit data bus. Each 4-bit RAM chip can only store 4 bits of data, and to combine this into an 8-bit memory module, we must connect the data lines of both chips appropriately.

Data Line 1 (D0) from Chip 1 and Data Line 1 (D0) from Chip 2 – Connect these to form bit 0 of the 8-bit data bus. Data Line 2 (D1) from Chip 1 and Data Line 2 (D1) from Chip 2 – Connect these to form bit 1 of the 8-bit data bus. Data Line 3 (D2) from Chip 1 and Data Line 3 (D2) from Chip 2 – Connect these to form bit 2 of the 8-bit data bus. Data Line 4 (D3) from Chip 1 and Data Line 4 (D3) from Chip 2 – Connect these to form bit 3 of the 8-bit data bus.

Thus, with two 16K by 4-bit RAM chips, we can create an 16K by 8-bit memory module simply by connecting their data lines to form an 8-bit bus.

3. Control Signals

Control signals like RAS (Row Address Strobe), CAS (Column Address Strobe), WE (Write Enable), and CE (Chip Enable) are connected in parallel between the two chips. Ensure that these control signals are synchronized so that both chips operate consistently.

Control Signal Connections:

RAS (Row Address Strobe) from Chip 1 and RAS (Row Address Strobe) from Chip 2 CAS (Column Address Strobe) from Chip 1 and CAS (Column Address Strobe) from Chip 2 WE (Write Enable) from Chip 1 and WE (Write Enable) from Chip 2 CE (Chip Enable) from Chip 1 and CE (Chip Enable) from Chip 2

Conclusion

Through precise configuration and connection of the 16K by 4-bit RAM chips within a 16K by 8-bit memory module, we can achieve a more versatile and efficient memory system. This process is fundamental in computer architecture and plays a critical role in enhancing the performance of memory-based systems.

For those interested in further details and deeper understanding, revising and practicing with homework is highly recommended. This hands-on experience will solidify the concepts and provide a strong foundation for future equipment development and integration.

Key Takeaways:

16K by 4-bit RAM chips can be connected to form a 16K by 8-bit memory module. Address lines (A0-A13) are used across both chips, making no additional address lines necessary. Data bus is formed by combining the respective data lines from each chip. Control signals are connected in parallel to ensure synchronization between chips.
