32 / 52 page Rev 1.0 / Apr. 2006 32 11 256Mbit (16Mx16bit) Mobile SDR Memory HY5S5B6GLF(P)-xE Series READ to WRITE Data from READ burst must be completed or truncated before a subsequent WRITE command can be issued. If trun- cation is necessary, the BURST TERMINATE command must be used, as shown in next fig. Read to Write Note : 1. Same bank, same ROW address: When the write command is executed at the same ROW address of the same bank as the preced- ing read command, the write command can be performed after an interval of no less than 1 clock. However, DQM must be set High so that the output buffer becomes High-Z before data input. 2. Same bank, different ROW address: When the ROW address changes, consecutive write commands cannot be executed; it is nec- essary to separate the two commands with a precharge command and a bank active command. 3. Different bank: When the bank changes, the write command can be performed after an interval of no less than 1 cycle, provided that the other bank is in the bank active state. However, DQM must be set High so that the output buffer becomes High-Z before data input.
