determining memory from the show version command

rakem

i need a bit of help regarding interpreting the sh version output in regards to the amout of memory

cisco 1601 (68360) processor (revision C) with 3584K/512K bytes of memory.
Processor board ID 14279505, with hardware revision 00000000
Bridging software.
X.25 software, Version 3.0.0.
Basic Rate ISDN software, Version 1.1.
1 Ethernet/IEEE 802.3 interface(s)
1 Serial(sync/async) network interface(s)
1 ISDN Basic Rate interface(s)
System/IO memory with parity disabled
2048K bytes of DRAM onboard 2048K bytes of DRAM on SIMM
System running from FLASH
8K bytes of non-volatile configuration memory.[\b]
6144K bytes of processor board PCMCIA flash (Read ONLY)

so i think its like this

the 3584K is the DRAM
the 512K is the ?????(RAM maybe)
the 8K is the NVRAM
the 6144K is the Flash Memory

2048K bytes of DRAM onboard 2048K bytes of DRAM on SIMM . . whats this refering too?

can someone help me out with this?
thanks

4MB of DRAM 6MB of FlashRAM

the 8k non-volatile memory is for something else.
