ASTM F726-06 吸附剂的吸附性能试验

This test method is to be used as a basis for comparison of adsorbents in a consistent manner. These tests are not appropriate for absorbent materials that are covered in Methods F 716.1.1 This test method covers laboratory tests that describe the performance of adsorbents in removing nonemulsified oils and other floating, immiscible liquids from the surface of water.1.2 The values stated in SI units are to be regarded as the standard.This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. Specific precautionary statements are given in 8.3.1.

JEDEC JEP106U.01-2006 生产商的标准识别码

The manufacturer’s identification code is defined by one or more eight (8) bit fields, each consisting of seven (7) data bits plus one (1) odd parity bit. The manufacturer’s identification code as shown in Table 1, is assigned, maintained and updated by the JEDEC office. It is a single field, limiting the possible number of vendors to 128. To expand the maximum number of identification codes, a continuation scheme has been defined. The code 7F, as shown in Table 1, indicates that the manufacturer’s code is beyond the limit of this field and the next sequential manufacturer’s identification field is used. Multiple continuation fields are permitted and when used, shall comprise of the identification code.

JEDEC JESD79E-2005 双重数据速度(DDR) SDRAM 规范要求

1. CKE is HIGH for all commands shown except SELF REFRESH. 2. BA0--BA1 select either the Base or the Extended Mode Register (BA0 = 0, BA1 = 0 selects Mode Register; BA0 = 1, BA1 = 0 selects Extended Mode Register; other combinations of BA0--BA1 are reserved; A0--A13 provide the op--code to be written to the selected Mode Register. 3. BA0--BA1 provide bank address and A0--A13 provide row address. 4. BA0--BA1 provide bank address; A0--Ai provide column address; A10 HIGH enables the auto precharge feature (nonpersistent), A10 LOW disables the auto precharge feature. 5. A10 LOW: BA0--BA1 determine which bank is precharged. A10 HIGH: all banks are precharged and BA0--BA1 are ”Don’t Care.” 6. This command is AUTO REFRESH if CKE is HIGH; SELF REFRESH if CKE is LOW. 7. Internal refresh counter controls row addressing; all inputs and I/Os are ”Don’t Care” except for CKE. 8. Applies only to read bursts with autoprecharge disabled; this command is undefined (and should not be used) for read bursts with autoprecharge enabled, and for write bursts. 9. DESELECT and NOP are functionally interchangeable. 10. Used to mask write data, provided coincident with the corresponding data. 11. Operation or timing that is not specified is illegal and after such an event, in order to guarantee proper operation, the DRAM must be powered down and then restarted through the specified initialization sequence before normal operation can continue. 12. VREF must be maintained during Self Refresh operation.
