What's kind of memory type of 80C51's data memory?

80c51

I'm puzzled by the type of 51's data memory, I'm not sure if it is DRAM or SRAM.

If anyone knows some thing about it. pls let me know.

Thanks & Regars!

It is SRAM. DRAMs are not used in low-end 8-bit microcontrollers.

But if it is SRAM, how could it make several KBs with 6T cell?
Or is there any new SRAM cells?


Thanks!

I am not exactly sure of the internal construction of 8051's SRAM. But it is sure that its SRAM and not DRAM.
