Not enough memory AND problem with using PROGMEM

Projects Programming
3

for to block of the code, the used ram is same value.

the code is huge, i define this arrays in private section of the class header.

some thing like this :

#ifndef iClass_h
#define iClass_h

#if (ARDUINO >= 100)
#include <Arduino.h>
#else
#include <WProgram.h>
#endif

class iClass {
	typedef void (*callback_function)(int, int, bool);
	public:
		iClass (uint16_t width, uint16_t height, callback_function setpix);
		void printTextToBuffer(byte buffer[], uint8_t query[]);
	private:
		uint16_t lcd_width, lcd_height;
		callback_function setPixel;
		uint8_t draw_cursor = 0;
		.
		.
		.
		const uint16_t splited_map1[178] PROGMEM = {...};
		const uint16_t splited_map2[170] PROGMEM = {...};
		const uint16_t splited_map3[175] PROGMEM = {...};
		const uint16_t splited_map4[171] PROGMEM = {...};
		const uint16_t splited_map5[176] PROGMEM = {...};
		const uint16_t splited_map6[20] PROGMEM = {...};
};

#endif

and for main code:

#include <SPI.h>
#include "LCD_Functions.h"
#include "iClass.h"

iClass ici(84,48,setPixel);

void setup() {
  lcdBegin();
  setContrast(50); 
}

void loop() {
  
}
