Micron решила, что пришло время DDR 333. DDR333 (частота 167MHz) имеет пропускную способность в 333Mbps и обратно совместима с DDR200 и DDR266. Вот её подробные спецификации: 167 MHz Clock, 333 MHz data rate VDD = +2.5V ±0.2V, VDDQ = +2.5V ±0.2V Bidirectional data strobe (DQS) transmitted/received with data Internal, pipelined double-data-rate (DDR) architecture; two data accesses per clock cycle Differential clock inputs (CK and CK#) Commands entered on each positive CK edge DQS edge-aligned with data for READs; center-aligned with data for WRITEs DLL to align DQ and DQS transitions with CK Four internal banks for concurrent operation Data mask (DM) for masking write data (x16 has two - one per byte) Programmable burst lengths: 2, 4, or 8 Concurrent Auto Precharge option supported Auto Refresh and Self Refresh Modes FBGA package available 2.5V I/O (SSTL\_2 compatible) tRAS lockout ( tRAP = tRCD) Источник новости: AnandTech
