What is the amount of time it takes the predecessor to read data from memory?

The time it takes for a predecessor to read data from memory, often referred to as memory latency, can vary depending on the type of memory being accessed. For example, accessing data from Level 1 (L1) cache typically takes a few cycles (1-4 ns), while accessing data from main RAM can take tens of nanoseconds (around 50-100 ns). In contrast, reading from slower storage media like SSDs or HDDs can take milliseconds. Overall, memory access times are crucial for overall system performance.
