For a 64 bit SRAM, the number of transistors for the memory only (excluding addressing/sensinglogic) are:

To calculate the number of transistors required for a 64-bit SRAM, we must first understand the basic architecture of an SRAM cell. Typically, a single SRAM cell is composed of 6 transistors (6T configuration).

Calculation Steps

1. Identify the Number of Bits:

   • In this case, we have a 64-bit SRAM.

2. Determine Transistors per Cell:

   • A standard SRAM cell uses 6 transistors.

3. Calculate Total Number of Transistors:

   • Total transistors for 64 bits = Number of bits × Transistors per bit $\text{Total Transistors} = 64 \, \text{bits} \times 6 \, \text{transistors/bit}$

4. Perform the Calculation: $\text{Total Transistors} = 384 \, \text{transistors}$

Final Answer

In total, for a 64-bit SRAM, the number of transistors required for the memory only (excluding addressing and sensing logic) is 384 transistors.
