A:Answer This model has 3 MB of read only memory and 154K of random access memory. the ROM houses the units firmware, logarithmic, exponential, and trigonometric functions.
The RAM consists of 56-bit registers (Not including the registers built into the CPU) Some of the registers are used for internal operations so the count may not match register count in the downloadable documentation for the calculator. If your looking for a calculator that has memory to spare the HP Prime is what I use for work related calculations It has 32MB of RAM and 256 MD of flash memory. includes a ton of apps for finance, triangles, statistics, ect.. Half of the RAM is free (around 16MB) and you can use HP Basic to program functionality to it that you need.
