MT40A512M16LY-062E IT:E Pin Configuration

Features of MT40A512M16LY-062E IT:E

The MT40A512M16LY-062E IT:E DDR4 SDRAM module is a high-speed dynamic random access memory that is internally organized into 16 banks (4 bank groups of 4 banks each for x4/x8 devices and 4 bank groups of 4 banks each for x16 devices). 2 bank groups containing 4 banks each). It uses double data rate (DDR) architecture for high-speed operation. The DDR4 architecture is based on the 8n prefetch architecture, which allows two data words to be transferred per clock cycle on the I/O pins. One read or write access to a device module consists of one 8n-bit wide, 4-clock cycle data transfer in the internal DRAM core and eight corresponding n-bit wide, 1/2 clock cycle data transfers. Masu. Transfers on I/O pins.

Read and write accesses to the device are burst-oriented, starting from a selected location and lasting for a burst length of eight or four chopped bursts in a programmed sequence. Operation begins with the registration of an ACTIVE command, followed by a READ or WRITE command. The address bits registered at the same time as the ACTIVE command are used to select the bank and row to access (BG[1:0] selects the x4/x8 bank group, BG0 selects the x16 bank group, etc.). BA[1:0] selects the bank and A[17:0] selects the row. Address bits registered at the same time as the READ or WRITE command select the starting column position for the burst operation. , used to determine whether to issue an automatic PRECHARGE command (via A10), and to 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 on and initialized in a predefined manner. The following sections provide details about device reset and initialization, register definitions, command descriptions, and device operation.

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