... KM29U64000T, KM29U64000IT PRODUCT INTRODUCTION The KM29U64000 is a 66Mbit(69,206,016 bit) memory organized as 16,384 rows by 528 columns. Spare sixteen columns are located from column address of 512 to 527. A 528-byte data register is connected to memory cell arrays accommodating data trans- fer 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 ...

... KM29U64000T, KM29U64000IT PIN DESCRIPTION Command Latch Enable(CLE) The CLE input controls the path activation for commands sent to the command register. When active high, commands are latched into the command register through the I/O ports on the rising edge of the WE signal. Address Latch Enable(ALE) The ALE input controls the path activation for address and input data to the internal address/data register ...

... KM29U64000T, KM29U64000IT NAND Flash Technical Notes (Continued) Error in write or read operation Over its life time, the additional invalid blocks may occur. Through the tight process control and intensive testing, Samsung mini- mizes the additional block failure rate, which is projected below 0.1% up until 1million program/erase cycles. Refer to the qualification report for the actual data ...

... KM29U64000T, KM29U64000IT Pointer Operation of KM29U64000 The KM29U64000 has three read modes to set the destination of the pointer. The pointer is set to "A" area by the "00h" command, to "B" area by the "01" command, and to "C" area by the "50h" command. Table 1 shows the destination of the pointer, and figure 2 shows the block diagram of its operations ...

... KM29U64000T, KM29U64000IT System Interface Using CE don’ t -care. For a 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 ...

... KM29U64000T, KM29U64000IT BLOCK ERASE The Erase operation is done on a block(8K Byte) basis. Block address loading is accomplished in two cycles initiated by an Erase Setup command(60H). Only address A 13 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 ...

... KM29U64000T, KM29U64000IT 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 (E6H) respectively. The command regis- ter remains in Read ID mode until further commands are issued to it. Figure 9 shows the operation sequence. ...

... KM29U64000T, KM29U64000IT 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 ...
