Final answer:
The SRAM UB/LB signals are responsible for transferring data between the SRAM and the processor in a computer system.
Step-by-step explanation:
The SRAM UB/LB signals stand for Upper Byte and Lower Byte signals. These signals are responsible for transferring data between the SRAM and the processor in a computer system.
When a processor wants to read or write data from/to the SRAM, it sends the address of the desired location and asserts the UB/LB signals to select the appropriate byte of data. The UB signal is used to select the upper 8 bits of the data bus, while the LB signal is used to select the lower 8 bits.
For example, if the processor wants to read a 16-bit value from the SRAM, it will assert both the UB and LB signals, allowing the entire data bus to be used. If it only wants to read or write the upper or lower byte of a 16-bit value, it will assert only the UB or LB signal, respectively.
