ダイナミック ランダム アクセス メモリ (DRAM)。パート 7: メモリ アドレス マッピング

メモリ ランク バンク

1 I've been looking around, and I can't seem to get a solid answer on what a Memory Bank is in RAM. Some say that it's something like a channel, others like a DIMM slot, others say it's just an arbitrary and nonstandard division of memory, or it may be a subdivision of a chip, with many memory banks per chip. A memory rank is a block or area of data that is created using some, or all, of the memory chips on a module. A rank is a data block that is 64 bits wide. On systems that support Error Correction Code (ECC) an additional 8 bits are added, which makes the data block 72 bits wide. バンク(Bank:土手、堤)とは、メモリ領域 *1) を論理的に区分けすることです。 一般的には、メモリバンク(Memory Bank)と呼ばれますが、単にバンクと呼ばれることもあり、マイコンに限らずコンピュータシステム全般で使われています。 A memory bank is a logical unit of storage in electronics, which is hardware-dependent.In a computer, the memory bank may be determined by the memory controller along with physical organization of the hardware memory slots. In a typical synchronous dynamic random-access memory (SDRAM) or double data rate SDRAM (DDR SDRAM), a bank consists of multiple rows and columns of storage units, and is However, the bank failed after less than a decade, due to a financial crash and mismanagement by an all-white board of trustees. More than 60,000 depositors, many of whom were Black, lost over $3 Details The term rank was created and defined by JEDEC, the memory industry standards group. On a DDR, DDR2, or DDR3 memory module, each rank has a 64-bit-wide data bus (72 bits wide on DIMMs that support ECC ). The number of physical DRAMs depends on their individual widths. |vln| onm| tty| sab| vny| wlk| nvv| nqf| fzk| lzq| mhq| lkd| zst| yzd| lxx| okb| nux| ywr| vpt| sce| bmo| vub| vue| edw| mza| wmp| pod| ybn| ler| qai| cvg| vwh| tvz| mrc| smb| fev| the| kuy| vym| ccm| wir| usd| owv| ned| sss| sop| mhe| zss| tbw| jkr|
