What Determines the Number of Bits in a Memory Bank?

💡 The Answer

• The number of bits in a column or row per bank equals the memory bus width.
• This is per chip, so each chip contributes the same number of bits.
• The bus width is a fixed value for a given system.
• Therefore, the bank's column/row capacity matches the bus width.
• The bank's total size is bits per column times bits per row times chip count.
