ʻO ka ʻokoʻa o nā hipa kāne ddr2, ddr3, a me ddr4
ʻO RAM ka pōkole no Random Access Memory. ʻIke pū ʻia ʻo "Random Access Memory", he ʻano hoʻomanaʻo no ka manawa pōkole. No laila, nalowale koke ka ʻike ke pio ka mana a i ʻole ke hoʻomaka hou ʻana o ke kamepiula.
Hoʻohana ʻia ka RAM no ka hoʻoholo ʻana i ka hana polokalamu, ʻo ia ke ʻano o ka nui o nā polokalamu e hiki ke hoʻohana ʻia e holo, ʻo ia ke kumu i ʻōlelo ʻia ai nā mea hoʻohana e kiʻi a kūʻai i nā ʻano RAM maikaʻi loa no ka mea aia lākou i waena o nā kumu nui i ka wikiwiki ʻana i ke kamepiula.
I kēia pou, e ʻike pū mākou e pili ana i nā ʻano o ka RAM a me ka ʻokoʻa ma waena o lākou i ʻike ʻoe i nā mea āpau, ʻoiai inā ʻoe e noʻonoʻo nei e hoʻololi i ka RAM i kāu kamepiula.

Nā ʻano RAM
ʻElua ʻano RAM, ʻo ka ʻano mua i kapa ʻia ʻo SINGLE IN LINE MEMORY MODULE a pōkole ʻia i "SIMM" kahi ʻano kahiko i hoʻohana mua ʻia me nā polokalamu 486DX2, aʻo ka ʻano ʻelua i kapa ʻia ʻo DUAL IN LINE MODORY, i pōkole. e like me DIMM a ua mahele ʻia i ʻekolu ʻano, ʻo ia hoʻi ʻo SDRAM DDRAM a me RDRAM.
ʻO ke ʻano mua he Single Data Rate Random Access Memory, i hoʻopau ʻia ʻo "SDRAM", ʻo ia kekahi o nā ʻano kahiko loa a ʻaneʻane ʻaʻohe hoʻohana no kēia ʻano i ko mākou manawa. Hoʻololi kēia ʻano i ka ʻike ma kahi wikiwiki a nāwaliwali loa a hoʻopau i ka nui o ka ikehu.
ʻO ke ʻano ʻelua, Double Data Rate-Synchronous DRAM, ua hoʻopau ʻia ʻo DDRAM. ʻO kēia ʻano hana i ka hana kiʻekiʻe ʻelua o ka hana o ka ʻano mua me ka hoʻopau ʻana i ka mana liʻiliʻi a he ʻekolu ʻano ʻano like ʻole, ʻo ia ka DD-RAM I - DD-RAM II - DD-RAM III e kū nei no DDR1 - DDR2. Memo DDR3.
ʻO ke kolu o ke ʻano, ʻo ia ka hoʻomanaʻo hoʻomanaʻo o ka Rambus a me ka "RDRAM" i hoʻopau ʻia ʻo Rambus Dynamic Random Access Memory, ʻike ʻia e ka wikiwiki kiʻekiʻe a me ke kumu kūʻai kiʻekiʻe ma mua o nā ʻano ʻē aʻe i ʻōlelo ʻia ma nā laina i luna, a he loea i ka hāʻawi ʻana. a me ka hoʻoili ʻana i ka ʻikepili ma waena o ka hoʻomanaʻo a me ka mea hana i nā wahi ʻoi aku ma mua o hoʻokahi. Ua kāpae ka hui i kēia ʻano ma muli o kāna kumukūʻai kiʻekiʻe me ka ʻoiaʻiʻo he mau hopena ikaika a DDR2 a me ke kumu kūʻai haʻahaʻa.
ʻO ka ʻokoʻa ma waena o nā hipa kāne ddr1 - ddr2 - ddr3 - ddr4
DDR1: ʻO ke ʻano kahiko a loaʻa ʻole, ddram mana mua.
DDR2: Loaʻa kēia ʻano a loaʻa i nā kikoʻī he nui a hoʻohana ʻia ma ke ʻano he kaʻina hana ma ka papapihi a me nā kamepiula kamepiula pū kekahi, ʻo kēia ʻano he ikehu kūpono a loaʻa ka volta a hiki i 1.8 GHz.
DDR3: He kūpono loa kēia ʻano no nā laptops a loaʻa iā ia nā pōmaikaʻi o ka hoʻonui ʻana i ka wikiwiki o ka hana ʻoiai e hōʻemi ana i ka hoʻohana ʻana i ka mana, akā kiʻekiʻe kona kumukūʻai i hoʻohālikelike ʻia me DDR2
