... K9K1208U0M-YCB0, K9K1208U0M-YIB0 PRODUCT INTRODUCTION The K9K1208U0M is a 528Mbit(553,648,218 bit) memory organized as 131,072 rows(pages) by 528 columns. Spare sixteen col- umns are located from column address of 512 to 527. A 528-byte data register is connected to memory cell arrays accommodating data transfer between the I/O buffers and memory during page read and page program operations. The memory array is made cells that are serially connected to form a NAND structure ...

K9K1208U0M-YCB0, K9K1208U0M-YIB0 Pointer Operation of K9K1208U0M Samsung NAND Flash has three address pointer commands as a substitute for the two most significant column addresses. ’00h’ command sets the pointer to ’A’ area(0~255byte), ’01h’ command sets the pointer to ’B’ area(256~511byte), and ’50h’ command sets the pointer to ’ ...

... K9K1208U0M-YCB0, K9K1208U0M-YIB0 System Interface Using CE don’t-care. For an easier system interface, CE may be inactive during the data-loading or sequential data-reading as shown below. The internal 528byte page registers are utilized as seperate buffers for this operation and the system design gets more flexible. In addition, for voice or audio applications which use slow cycle time on the order of u-seconds, de-activating CE during the data-loading and read- ing would provide significant savings in power consumption ...

... K9K1208U0M-YCB0, K9K1208U0M-YIB0 BLOCK ERASE The Erase operation is done on a block(16K Byte) basis. Block address loading is accomplished in three cycles initiated by an Erase Setup command(60h). Only address block address loading initiates the internal erasing process. This two-step sequence of setup followed by execution command ensures that memory contents are not accidentally erased due to external noise conditions ...

... K9K1208U0M-YCB0, K9K1208U0M-YIB0 READ ID The device contains a product identification mode, initiated by writing 90h to the command register, followed by an address input of 00h. Two read cycles sequentially output the manufacture code(ECH), and the device code (76H) respectively. The command regis- ter remains in Read ID mode until further commands are issued to it. Figure 9 shows the operation sequence. ...

... K9K1208U0M-YCB0, K9K1208U0M-YIB0 READY/BUSY The device has a R/B output that provides a hardware method of indicating the completion of a page program, erase and random read completion. The R/B pin is normally high but transitions to low after program or erase command is written to the command reg- ister or random read is started after address loading. It returns to high when the internal controller has finished the operation. The pin is an open-drain driver thereby allowing two or more R/B outputs to be Or-tied ...
