The Function of MT40A512M16LY-062E IT:E

The MT40A512M16LY-062E IT:E DDR4 SDRAM module is a high-speed dynamic random-access memory configured with sixteen banks internally (4 bank groups with 4 banks each for x4/x8 devices, and 2 bank groups with 4 banks each for x16 devices). It uses a double data rate (DDR) architecture for high-speed operation. The DDR4 architecture is based on an 8n-prefetch architecture, allowing it to transfer two data words per clock cycle at the I/O pins. A single read or write access for a device module effectively consists of a single 8n-bit-wide, four-clock-cycle data transfer at the internal DRAM core and eight corresponding n-bit-wide, one-half-clock-cycle data transfers at the I/O pins.

Read and write accesses to the device are burst-oriented, starting at a selected location and continuing for a burst length of eight or a chopped burst of four in a programmed sequence. Operation begins with the registration of an ACTIVE command, followed by a READ or WRITE command. The address bits registered coincident with the ACTIVE command are used to select the bank and row to be accessed (BG[1:0] selects the bank group for x4/x8, and BG0 selects the bank group for x16; BA[1:0] select the bank, and A[17:0] select the row). The address bits registered coincident with the READ or WRITE command are used to select the starting column location for the burst operation, determine if the auto PRECHARGE command is to be issued (via A10), and select BC4 or BL8 mode on-the-fly (OTF) (via A12) if enabled in the mode register.

Before normal operation, the device must be powered up and initialized in a predefined manner. The following sections provide detailed information on device reset and initialization, register definition, command descriptions, and device operation.

Note: The NOP command is allowed only when exiting maximum power-saving mode or when entering gear-down mode.
